具体实施方式 DETAILED DESCRIPTION

[0038] 为使审查委员对本发明的结构特征及所达成的功效有更进一步的了解与认识,谨佐以较佳的实施例及配合详细的说明,说明如后: [0038] In order to examine members of the structural features of the present invention and the effect reached a better understanding and awareness of honor accompanied by examples and with a detailed description of the preferred embodiments, are described next:

[0039] 请参阅图3,其为本发明的一较佳实施例的方块图。 [0039] Refer to Figure 3, a block diagram of an example of a preferred embodiment of the present invention it. 如图所示,本发明的缓冲器的重置系统包含有一控制单元30、一重置旗标13与一覆写旗标16,重置旗标13与覆写旗标16皆设于一缓冲器10。 As shown, the buffer system of the present invention comprises resetting a control unit 30, a flag 13 and a reset override flag 16, flag 13 is reset to overwrite flag 16 are provided in a buffer 10. 控制单元30用于确认重置旗标(resettable flag) 13的状态与确认并改变覆写旗标(overwriteable flag) 16,以控制缓冲器10的资料读取与写入。 The control unit 30 is used to confirm the reset flag (resettable flag) state with 13 confirmed and change overwrite flag (overwriteable flag) 16, 10 to control the buffer data read and write. 控制单元30确认重置旗标13被设定,之后控制单元30允许呼叫重置功能以重置缓冲器10,也就是重置缓冲器10的开始指标回复至缓冲器10的起始位址,如此第三处理单元24即可在第二处理单元22读取缓冲器10的资料而无法处理时,可重新读取缓冲器10原有的资料而进行处理。 The control unit 30 to confirm the reset flag 13 is set, then the control unit 30 allows the call to reset function to reset the buffer 10, which is the starting index reset buffer 10 return to the starting address of the buffer 10, So the third processing unit 24 to the second processing unit 22 reads the data buffer 10 can not handle, it can re-read the original data buffer 10 and processing. 若重置旗标13被设定成一非重置参数,之后控制单元30便无法重置缓冲器10,最初将重置旗标13设定为重置参数,当有任何资料覆写于缓冲器10的资料时,重置旗标13 将会自动设定为非重置旗标。 If the reset flag 13 is set to a non-reset the parameters, then the control unit 30 can not reset buffer 10 initially resets the flag 13 is set to reset the parameters, if there is any data in the buffer is overwritten When the data 10, 13 will automatically reset flag set to non reset flag.

[0040] 控制单元30设定覆写旗标16为一非覆写参数值时,即为逻辑中的”假” (False), 是无法将资料覆盖缓冲器10的原有资料,请一并参阅图4所示,当覆写旗标16设定为一非覆写参数值时,资料将写入缓冲器10,直到结束指标到达缓冲器10的最后位址时,无法将资料覆写至缓冲器10,也就是说缓冲器10已储存旧资料6,当覆写旗标16设定为一非覆写参数值时,新资料可由开始旗标2之后写入缓冲器10,直到写满缓冲器10的容量,即是结束旗标4移至缓冲器10的尾端,如此可避免第一处理单元20后续写入资料于缓冲器10,而覆盖缓冲器10内原有的资料,使第二处理单元22或第三处理单元24读取缓冲器10的资料, 仍可保留缓冲器10原有的资料。 When [0040] The control unit 30 is set to overwrite flag 16 is a non-overwrite parameter value is logic "false" (False), is unable to cover data buffer 10 of the original data, please be See the figure, when the overwrite flag 16 is set to a non-overwritten parameter values, the data written to the 4 buffer 10 until the end of the index reaches the last address of the buffer 10, data can not be overwritten to buffer 10, that buffer 10 has stored old data 6, when the overwrite flag 16 is set to a non-overwritten parameter values, the new data can be written to the flag after starting second buffer 10 until filled capacity of the buffer 10, that is, the flag trailing end 4 to move the buffer 10, so the first processing unit 20 can avoid a subsequent write data in the buffer 10, and cover 10 of the original data in the buffer, the first second processing unit 22 or the third processing unit 24 reads the data buffer 10, will retain 10 existing data buffer. 控制单元30设定覆写旗标16为一覆写参数值时,即为逻辑中的”真”(Ture),缓冲器10可被覆写资料。 The control unit 30 is set to overwrite overwrite flag 16 is a parameter value, that is the logic of the "true" (Ture), data buffer 10 can be overwritten.

[0041] 以下是举一实施例,而对本发明进行说明。 [0041] The following is one example cited, while the present invention will be described. 当第一处理单元20储存一第一资料至缓冲器10后,第二处理单元22会读取缓冲器10的第一资料以进行处理。 When the first processing unit 20 stores a first data to the buffer 10, the second processing unit 22 reads the first data buffer 10 for processing. 第二处理单元22于处理第一资料时,是会发送一回应讯息至控制单元30,通知控制单元30可处理第一资料。 The second processing unit 22 at the time of processing the first data, a response message is sent to the control unit 30, notifies the control unit 30 may process the first data. 若第二处理单元22可处理第一资料时,控制单元30即依据表示可处理资料的回应讯息设定覆写旗标为覆写参数值,让第一处理单元20可覆写资料至缓冲器10。 If the second processing unit 22 may process a first data, i.e., the control unit 30 based on the processing data represents the response message override flag set parameter values for the override, so that the first processing unit 20 may overwrite the data from the buffer 10. 若第二处理单元22无法处理第一资料时,控制单元30将会确认缓冲器10的覆写旗标16,若重置旗标设定为逻辑中的”真”,即会重置缓冲器10,并即依据表示无法处理资料的回应讯息发送一交换讯息至第三处理单元24,也就是说当第二处理单元22无法处理第一资料时,控制单元30 会交换第二处理单元22与第三处理单元对,让第三处理单元M取代第二处理单元22。 If the second processing unit 22 can not handle the first data, the control unit 30 will confirm buffer overwrite flag 16 10, if the reset flag set to a logic "true", ie reset buffer 10, and said it could not deal with information that is based on the response message exchange sends a message to the third processing unit 24, that is to say when the second processing unit 22 can not handle the first data, the control unit 30 will be exchanged with the second processing unit 22 a third processing unit, so that the third processing unit of the second processing unit 22 M substituent.

[0042] 此外,控制单元30于发送驱动讯息的同时亦会重置缓冲器10并设定重置旗标13 为重置参数值,以重置缓冲器10,使开始指标回复指向缓冲器10的第一资料的起始位置, 让第三处理单元M可以从缓冲器10储存第一资料的起始位置开始读取第一资料,如此即可解决第三处理单元M在第二处理单元22无法处理缓冲器10的资料时,无法重新读取缓冲器10原有资料的问题,以提高缓冲器10的使用效能。 [0042] In addition, the control unit 30 to send a message at the same time will reset drive buffer 10 and sets the reset flag to reset the parameter values 13 to reset the buffer 10 so that the start indicator pointing to the buffer 10 replies the starting position of the first data, so that the third processing unit M can start reading the first data from the first storing start position data buffer 10, so to solve the third processing unit in the second processing unit 22 M We can not handle data buffer 10, the buffer 10 can not be re-read issues of the original data in order to improve the effectiveness of the use of the buffer 10. 上述,第三处理单元M于处理第一资料时,亦会发送回应讯息至控制单元30,使控制单元30设定覆写旗标13为覆写参数值,让第一处理单元20可接续覆写资料至缓冲器10。 Above, the third processing unit M at the time of processing the first data, will send a reply message to the control unit 30, the control unit 30 sets a flag 13 is overwritten overwrite parameter values, so that the first processing unit 20 may continue cover write data to the buffer 10. 上述,若覆写旗标被设定为覆写参数值且第一处理单元20写入足够资料至缓冲器10以覆写一些资料,之后重置旗标13为非重置参数值。 Above, if the override flag is set to the parameter value and overwrite the first processing unit 20 writes data to the buffer 10 is sufficient to override some of the information, after resetting the flag 13 is non-reset parameter values.

[0043] 另外,若之后第一处理单元20无法处理缓冲器10的资料,第三处理单元M亦无法处理缓冲器10的资料时,其会发送表示无法处理资料的回应讯息至控制单元30,之后若有任何其他处理单元时,此时控制单元30即会发送交换讯息至其他处理单元,以交换第三处理单元对,让其他处理单元取代第三处理单元24,同时控制单元30会重置缓冲器10并设定重置旗标13为重置参数。 When [0043] In addition, if after the first processing unit 20 can not process data buffer 10, the third processing unit M also can not handle the data buffer 10, which will send response message can not be processed indicates to the control unit 30 of the information, If after any other processing unit, now the control unit 30 that is sent to other processing units exchange messages in exchange for a third processing unit, so that other processing units replace a third processing unit 24, while the control unit 30 resets buffer 10 and set the reset flag 13 is reset parameters.

[0044] 请参阅图5,其为本发明的另一较佳实施例的方块图。 [0044] Refer to Figure 5, a block diagram of another preferred embodiment of the present invention it. 如图所示,本发明的缓冲器的重置系统可应用于网路的串流系统。 As shown, the buffer reset system of the present invention can be applied to Internet streaming system. 此串流系统包含有一下载单元40、第一缓冲器50、 一解码模组60、一第二缓冲器70与一播放单元80。 This system comprises a streaming download unit 40, the first buffer 50, a decoder module 60, a buffer 70 and a second playing unit 80. 下载单元40藉由网际网路下载一网路资料并写入第一缓冲器50。 Download unit 40 by a network data download Internet and into the first buffer 50. 网路资料可为WMA、WMV或MP3的资料格式或任何其他格式,。 Network data for WMA, WMV or MP3 data format or any other format. 由于起初不确定解码模组60的一第一解码单元62、一第二解码单元64与一第三解码单元66是否可解码第一缓冲器50内的网路资料。 Since the initial uncertainty of a first decoding unit decoding module 60 of 62, a second decoding unit 64 and a third decoding unit 66 can decode whether the first buffer 50 within the network data. 第一缓冲器50的覆写旗标56初始设定为非覆写参数,所以可确保切换解码单元。 The first buffer 50 of 56 Overwrite flag set to non overwritten initial parameters, it is possible to ensure that the switching decoder.

[0045] 解码模组60,用于解码第一缓冲器50的网路资料,解码模组60的第一解码单元62、第二解码单元64与第三解码单元66,分别用于针对WMA、WMV以及MP3的资料格式进行解码。 [0045] decoding module 60 for decoding the first network data buffer 50, the decoder module 60 of the first decoding unit 62, the second decoding unit 64 and the third decoding unit 66, respectively, for for WMA, WMV and MP3 data formats can be decoded. 当第一缓冲器50储存有网路资料时,第一解码单元62将先读取第一缓冲器50的网路资料,若第一缓冲器50的网路资料为WMA格式时,第一解码单元62即可进行解码,并发送表示可以处理的回应讯息至控制单元30,以让控制单元30得知第一解码单元62可解码网路资料,此时控制单元30会设定第一缓冲器的覆写旗标56为覆写参数值,让下载单元40 可持续储存网路资料至第一缓冲器50。 When the first buffer 50 stores a data network, the first decoding unit 62 first reads the first network data buffer 50, if the first buffer network data 50 for WMA format, the first decoding unit 62 can be decoded and transmits response message indicates to the control unit 30 can be handled in order to allow the control unit 30 that the first decoding unit 62 may decode network information, then the control unit 30 will set a first buffer The flag 56 is overwritten overwrite parameter values, so that the download unit 40 sustainable store network data to the first buffer 50.

[0046] 若,下载单元40所下载的网路资料为MP3格式时,第一解码单元62将无法进行解码,此时第一解码单元62会发送表示无法处理的回应讯息至控制单元30,让控制单元30得知第一解码单元62无法解码第一缓冲器50的网路资料。 [0046] if the download unit 40 download Internet data to MP3 format, the first decoding unit 62 will not be decoded, then the first decoding unit 62 indicates response message will be sent to the control unit 30 can not handle, so The control unit 30 that the first decoding unit 62 can not decode the first buffer network data (50). 控制单元30随即会发送交换讯息至第二解码单元64,而交换第一解码单元62与第二解码单元64,使第二解码单元64取代第一解码单元62,同时会重置第一缓冲器50,让第二解码单元64可重新读取第一缓冲器50原有的网路资料,即读取第一解码单元62所读取而无法解码的网路资料。 The control unit 30 then exchange messages will be sent to the second decoding unit 64, and the first decoding unit 62 and the second decoding unit 64 exchange, the second decoding unit 64 instead of the first decoding unit 62, while the first buffer is reset 50, so that the second decoding unit 64 can re-read the first original network data buffer 50, which reads the first decoding unit 62 reads network data can not be decoded.

[0047] 由于,第二解码单元64是针对WMV格式的网路资料进行解码,所以第二解码单元64亦无法对MP3格式的网路资料进行解码。 [0047] Since the second decoding unit 64 for network data to decode WMV format, so the second decoding unit 64 will not be able to network data to decode MP3 format. 此时,第二解码单元64亦会发送表示无法处理的回应讯息至控制单元30,以让控制单元30发送驱动讯息至第三解码单元66,而交换第二解码单元64与第三解码单元66,让第三解码单元66取代第二解码单元64,并再重置第一缓冲器50。 At this time, the second decoding unit 64 will respond to messages sent to the control unit represents can not handle 30 to allow the control unit 30 sends a message to the third decoding unit drive 66, and the switching of the second decoding unit 64 and a third decoding unit 66 , the decoding unit 66 so that the third substituent second decoding unit 64, a first buffer 50 and then resets. 让第三解码单元66可重新读取第一缓冲器50的网路资料。 Let a third decoding unit 66 can re-read the first network data buffer 50.

[0048] 由于第一缓冲器50所储存的网路资料的格式符合第三解码单元66可解码的资料格式,所以第三解码单元66将发送表示可处理的回应讯息至控制单元30,控制单元30将会依据回应讯息设定覆写旗标56为覆写参数值,使下载单元40可允许储存网路资料至第一缓冲器50,而覆盖原有的网路资料,让第三解码单元66可持续读取第一缓冲器50的网路资料而进行解码。 [0048] Since the format of the first buffer 50 network data stored in line with the third decoding unit 66 can decode the data format, the third decoding unit 66 sends the process represents a response message to the control unit 30, a control unit 30 will be set based on response message overwrites the flag 56 is overwritten parameter values, so that the download unit 40 may allow the storage network data to the first buffer 50, and overwrite the existing network information to enable third decoding unit read the first 66 sustainable network data buffer 50 and decoded.

[0049] 若,下载单元40所下载的网路资料的格式并非为WMA、WMV以及MP3时,由于解码模组60的解码单元62、64、66皆无法解码第一缓冲器50所储存的网路资料,加上控制单元30于此网路串流系统亦无法侦测到有其它解码单元存在,也就是代表此网路串流系统有误,而无法解码第一缓冲器50所储存的网路资料。 [0049] If, format download unit 40 downloads the network data is not as WMA, WMV and MP3, since the decoding unit decoding module 60, 64, 66 are not decode stored in the first buffer 50 network road, combined with a control unit 30 for this network streaming system will not be able to detect that there exist other decoding unit, which is representative of this network streaming system is wrong, but can not decode the first buffer 50 stored network road information.

[0050] 上述,第一解码单元62、第二解码单元64或第三解码单元66解码网路资料后,所产生的解码资料会储存至第二缓冲器70。 [0050] said first decoding unit 62, decoding unit 64 after the second or third decoding unit 66 decodes network data, the resulting decoded data will be saved to the second buffer 70. 之后,播放单元80会读取第二缓冲器70内的解码资料以进行播放。 After playing unit 80 reads the second decoding data buffer 70 is to be played. 在此实施例中,由于解码模组60所产生的解码资料的格式,是符合播放单元80可播放资料的格式,所以第二缓冲器70不需设置重置旗标与覆写旗标。 In this embodiment, since the format decoding module 60 generates decoded data is in line with the format data playback unit 80 can play, so the second buffer 70 without setting reset flag and overwrite flag. 在这实施例中,覆写旗标初始设定为”真”,并且第二缓冲器70相当于传统的环形缓冲器,然而第二缓冲器70亦可应用于不同的资料格式。 In this embodiment, the override flag initially set to "true", and the second buffer 70 equivalent to the traditional ring buffer, however, the second buffer 70 can be applied to different data formats.

[0051] 请参阅图6,其为本发明的一较佳实施例的流程图。 [0051] Please refer to FIG. 6, a flow diagram of one of its preferred embodiments the present invention. 为了便于说明,此实施例是配合图3进行说明。 For convenience of explanation, this embodiment is described with FIG. 3. 当不确定系统的处理单元22、24是否可处理缓冲器10所储存的资料时, 可先设定缓冲器10的覆写旗标16为非覆写参数值,让第一处理单元20无法储存资料至缓冲器10,以避免系统的处理单元22、24皆无法处理缓冲器10的资料时,第一处理单元20尚接续储存资料至缓冲器10而覆盖缓冲器10原有的资料而遗失。 When in doubt whether the system processing unit 22, 24 may process the data stored in the buffer 10, it can be set to override the flag buffer 10 16 non-overwrite parameter values, so that the first processing unit 20 can not be saved When the data to the buffer 10, in order to avoid the system of processing units 22 and 24 are unable to process data buffer 10, a first processing unit 20 still continue to store data to the buffer 10 and cover 10 of the original data buffer and lost. 如步骤SlO所示,当第一处理单元20写入资料至缓冲器10时,控制单元30即会设定缓冲器10的覆写旗标16为非覆写参数值,让缓冲器10无法覆写资料。 As step SlO, when the first processing unit 20 writes data to the buffer 10, ie, the control unit 30 will set the overwrite flag buffer 10 16 non-overwrite parameter values, so that the buffer 10 can not cover write data.

[0052] 第二处理单元22即会读取缓冲器10的资料并进行处理,且依据处理资料的状态对应发送回应讯息至控制单元30。 [0052] i.e., the second processing unit 22 reads the data buffer 10 and processed, and the processing of data in accordance with the state of the corresponding response message sent to the control unit 30. 控制单元30如步骤S12所示,接收到回应讯息后,即会进一步执行步骤S14,依据回应讯息确认第二处理单元22是否可以处理缓冲器10的资料, 若第二处理单元22可以处理缓冲器的资料,控制单元30即会执行步骤S16,设定覆写旗标16为覆写参数值,以让缓冲器10可覆写资料,使得第二处理单元22可持续读取缓冲器10 的资料并进行处理。 The control unit 30 as shown in step S12, after receiving the response message, i.e. further perform step S14, the confirmation response message according to the second processing unit 22 can process data buffer 10, if the second processing unit 22 may be processing buffer data, i.e., the control unit 30 executes step S16, the flag 16 is set override override parameter values to buffer 10 so that data can be overwritten, so that the second processing unit 22 reads the data buffer 10 Sustainable and processed.

[0053] 假若,第二处理单元22所发送的回应讯息表示无法处理资料,控制单元30在执行步骤S14时将会依据回应讯息而得知,并且执行步骤S18,侦测是否存在有其他处理单元, 以图3为例,控制单元30将会侦测到有第三处理单元24。 [0053] If the second processing unit 22 transmits the response message indicates the information can not be processed, when unit 30 S14 will be learned response message in accordance with step control, and executes step S18, the processing to detect whether there are other units in Figure 3 as an example, the control unit 30 will detect a third processing unit 24. 此时,控制单元30执行步骤S19, 重置缓冲器10,并且发送交换讯息至第三处理单元24,以交换第三处理单元24与第二处理单元22,让第三处理单元24读取缓冲器10原有的资料而进行处理。 At this time, the control unit 30 executes step S19, the reset buffer 10, and sends a message to the third exchange processing unit 24, in exchange for a third processing unit 24 and the second processing unit 22, the processing unit 24 so that the third read buffer 10 of the original data and processing. 随后,即重复执行步骤S12与步骤S14,若第三处理单元M可处理缓冲器10的资料,即进行步骤S16,并接续进行步骤S17,若第三处理单元M亦无法处理时,则又进行步骤S18,此时由于控制单元30已侦测不到有其他处理单元存在,所以如步骤S20所示,代表此系统错误而无法处理缓冲器10 的资料。 Subsequently, i.e., repeat step S12 and step S14, if the third processing unit M may process data buffer 10, i.e., step S16, and continue to step S17, if the third processing unit M also can not be processed, then they were step S18, the control unit 30 at this time because there have been unable to detect the presence of other processing units, so as shown in step S20, the representative system error and can not process data buffer 10.

[0054] 控制单元30于上述步骤S12,若未接收到回应讯息时,控制单元30会进行步骤S22,侦测缓冲器10是否被填满,因为覆写旗标设定为”假”,所以缓冲器将会填满,且缓冲器10储存资料并无关于资料被处理单元所读取,缓冲器10若未被填满资料时,则更多资料被写入(如步骤S10),并再一次确认及传送回应讯息(如步骤S12)。 When [0054] The control unit 30 in the above-described step S12, if no response message is received, the control unit 30 will be step S22, the buffer 10 to detect whether or not filled, since the overwrite flag is set to "false", so will fill the buffer, and the buffer 10 does not store information about the data to be read by the processing unit, the buffer 10 If it is not time to fill the information, the more information is written (e.g., step S10), and then a confirmation and transmission response message (as in step S12). 若缓冲器10已被填满资料时,控制单元30则执行步骤S24,持续等待回应讯息。 If the data buffer 10 has been filled, the control unit 30 executing step S24, the sustained response message waiting. 之后,控制单元30于接收到回应讯息后,则执行步骤S26,此步骤同于上述步骤S14。 Thereafter, the control unit 30 after receiving the response message, it executes a step S26, this step differs from the above-described step S14. 若回应讯息表示可处理缓冲器10的资料,则执行步骤S16,若回应讯息表示无法处理缓冲器10的资料,则执行同于步骤S18的步骤S28。 If the response message represents process data buffer 10, perform step S16, the response message if said it could not process data buffer 10, step S18 to step S28 with. 若控制单元30侦测没有存在其他处理单元时,是如步骤S20所示,表示系统错误, 若有处理单元存在则进行步骤S29,此步骤同于步骤S19。 If the control unit 30 does not detect the presence of other processing units, is as shown in step S20, the system is wrong, if the presence of the processing unit proceeds to step S29, this step differs from step S19. 随后重复执行步骤S24。 Then repeat Step S24.

[0055] 请参阅图7,其为本发明的另一较佳实施例的流程图。 [0055] See Figure 7, a flow chart of another embodiment of the present invention, its preferred embodiments. 此实施例为控制单元设定缓冲器的覆写旗标为覆写参数值后的处理流程。 This embodiment is a control unit to set the buffer overwrite flag overwrites parameter values for the post-processing. 此实施例同样配合图3进行说明。 Also with this embodiment is described in Figure 3. 由于缓冲器10的覆写旗标16设定为覆写参数值,所以如步骤S30所示,第一处理单元20可写入资料至缓冲器10。 Since the buffer 10 is overwritten flag 16 is set to override the parameter value, as shown in step S30, the first processing unit 20 may write data to the buffer 10. 之后,第二处理单元22会先读取缓冲器10的资料并进行处理,且依据处理资料的状态发送回应讯息。 Thereafter, the second processing unit 22 will first read data buffer 10 and processed, and the processing of data according to transmission status response message. 如步骤S32所示,当控制单元30接收到回应讯息后会执行步骤S34,若回应讯息表示第二处理单元22可处理缓冲器10的资料时,即如步骤S36所示,表示系统正常,第二处理单元22将接续读取缓冲器10的资料并进行处理。 When as shown in step S32, when the control unit 30 receives the response message performs step S34, if the response message indicates data buffer 22 may process a second processing unit 10, i.e., as shown in step S36, that the system is normal, the first Second processing unit 22 will continue to read data buffer 10 and processed.

[0056] 若,回应讯息表示第二处理单元22无法处理资料时,控制单元30则进行步骤S38, 侦测是否有其他处理单元存在,于此实施例系侦测尚有第三处理单元M存在,所以进行步骤S39,重置缓冲器10并交换第三处理单元M与第二处理单元22,让第三处理单元M取代第二处理单元22,交换完成后则重复执行步骤S32。 [0056] If the response message indicates the second data processing unit 22 can not be processed, the control unit 30 proceeds to step S38, to detect whether there exists another processing unit, in this embodiment of the system to detect the presence of yet a third processing section M , it proceeds to step S39, to reset the buffer 10 and a third switching processing unit M and the second processing unit 22, so that the third place of the second processing unit processing unit 22 M, after the exchange is complete repeat step S32. 之后,若第三处理单元M亦无法处理缓冲器10的资料时,由于系统已没有其他处理单元存在可以进行交换,所以如步骤S40 所示,表示此系统错误。 Thereafter, if the third processing unit M also can not handle data buffer 10, because the system has been without the presence of other processing units can be exchanged, so that as shown in step S40, this indicates a system error.

[0057] 于上述步骤S32,若控制单元30持续未接收到回应讯息时,控制单元30会如步骤S42所示,侦测缓冲器10是否被填满,缓冲器10若未被填满资料时,则更多资料被写入(如步骤S10),并再一次确认及传送回应讯息(如步骤S12),若缓冲器10已被填满资料时,则直接认定此系统正常。 When [0057] the above-described step S32, when the control unit 30 receives the response message is not continued, the control unit 30 will be as shown in step S42, the buffer 10 to detect whether or not filled, if not the buffer 10 is filled with data , the more information is written (as in Step S10), and once again confirm and transmission response message (as in step S12), if the data buffer 10 has been filled, then direct that this system is normal. 其是因为起初会设定覆写旗标16为覆写参数值即表示此系统的其中的一处理单元可处理缓冲器10的资料,所以直接认定此系统正常。 It is because at first will override the flag 16 is set to override the parameter values of this system means that a processing unit which can process data buffer 10, so direct that this system is normal. 本发明设定覆写旗标为覆写参数值不一定需经过第五图的流程,若确定系统的处理单元可处理缓冲器的资料时,亦可直接设定覆写旗标为覆写参数值。 The present invention is set to override the flag to override the parameter values are not necessarily subject to the fifth diagram of the process, if the system determines the information processing unit can handle buffer, or directly overwrite flag is set to override the parameters value.

[0058] 综上所述,本发明的缓冲器的重置系统及其方法是藉由设置重置旗标于缓冲器, 让两处理单元于交换时,重置缓冲器,如此交换后的处理单元即可重新读取前一处理器所读取而无法处理的资料。 [0058] In summary, reset the system and method of the present invention is a buffer by setting a flag in the buffer is reset, so that both the processing unit at the time of the exchange, the buffer is reset, so exchanged processing unit to re-read the previous data processor can not handle the read. 又,重置旗标将可自动设定而允许控制单元得知系统是否需要重置。 Further, reset the flag will be set automatically and allows the control unit to know whether the system needs to be reset. 另外,本发明更设置覆写旗标于缓冲器,若在不确定系统的处理器是否可处理缓冲器的资料时,为了避免缓冲器的资料被后续写入的资料覆盖而遗失,可藉由设定覆写旗标为非覆写参数值,让缓冲器无法覆写资料直至确定有处理单元可处理缓冲器的资料,覆写旗标将会设定为覆写参数,使缓冲器像一般环形缓冲器一样,如此即可确保缓冲器的资料不会遗失,而提高缓冲器的使用效能。 Further, the present invention may be more settings to overwrite flag in the buffer, if the possibility of processing data buffers in an uncertain system's processor, in order to avoid data coverage data buffer is written and subsequent loss, can be Setting overwrite flag is non-overwrite parameter values, so that the buffer can not overwrite the data until it is determined there is a processing unit can process data buffer, overwriting the flag will be set to override the parameters so that the buffer as general Like the ring buffer, the buffer so you can ensure that the information will not be lost, and to improve the use of performance buffers. 若覆写旗标的初始状态设定为覆写参数时,缓冲器就相当于环形缓冲器,将资料读进缓冲器前时,允许重置并切换处理单元。 If you overwrite the initial state of the flag is set to override the parameters, the buffer is equivalent to the ring buffer when the data is read into the buffer before allowing reset and switching processing unit. [0059] 以上所述,仅为本发明的一较佳实施例而已,并非用来限定本发明实施的范围,举凡依本发明权利要求范围所述的形状、构造、特征及精神所为的均等变化与修饰,均应包括于本发明的权利要求范围内。 [0059] Equalization of the above, the present invention is only a preferred embodiment only, not intended to limit the scope of embodiments of the present invention, Jufan under this shape, structure, characteristics and spirit of the claimed invention, the scope of the claim of the order Changes and modifications, including the rights of the present invention should be in the required range.
