When the transfer status flag 21 of the control instruction storage means 12 of 10 is set to enable command execution, the input/output process 27 is performed again. If the transfer status flag 21 indicates that the command has ended abnormally, and if the transfer destination means 17 is not set, the operation input step 26 is performed again.

Next, the operation of the input/output process 27 will be explained in detail.

Waiting for the start time a 31 is an input/output start process in which input or output of digital information is started according to the processing instruction 15. 32 is an input/output of information. If a time error occurs in the input/output process 27, the input/output monitor 33 monitors whether the input/output process is completed without error, and performs processing according to the content of the time error processing flag 24 in the time information storage means 13. Time error processing error, a 34 indicates that the input/output process 27 has been completed without an error, and sets the transfer status flag 21 of the control command storage means 12. 35 indicates an error occurred during the input/output process 27. In the input/output abnormal notification process, which sets the transfer status flag 21 of the control instruction storage means 12 to indicate that the input/output has ended abnormally, the time flag 2
The operation will be explained by taking as an example the case where 0 indicates that there is a time designation and audio information is stored in the input storage means 3 from the audio input/output means 1. First, in the operation input step 26, when the operation method is inputted from the operation input means 6, the main control means 5 uses the control information storage means 10 connected to the voice input/output means 1.
The processing command 15 of the control command storage means 12 is a code indicating information input, the transfer source means 16 is a code indicating voice input means 1, the transfer destination means 17 is a code indicating storage means 3, and the time flag 20 is a code indicating time information. A code indicating that the control information is set and the transfer status flag 21 is set to indicate that the command is executable. Transfer information amount 18 and address 19 are set to predetermined values. Input/output of time information storage means 13 The start time 22 and input/output end time 23 are set to predetermined values, and the time error processing flag 24 is a code that continues processing even if there is a time error, a code that causes abnormal termination if there is a time error, and a code that causes re-execution. In addition, the processing command 15 of the control command storage means 12 of the control information storage means 7 connected to the storage means 3 is set as a code indicating information output, and the transfer source means 16 is set as the voice input means 1. The transfer destination means 17 is a code indicating the storage means 3, the time flag 20 is a code indicating that there is no time information, and the transfer status flag 21 is a code indicating that the control information is set. do. Transfer information amount 18 and address 19 are the same values as those related to audio input/output means l.
Even if the instruction analysis process 29 is performed, the instruction analysis process 29 first waits until the transfer status flag 21 becomes a code indicating that the control information is set and the instruction can be executed. , confirm that the processing instruction 15 is a code indicating that the copy transfer source means 16 indicating information input is a code indicating the audio input/output means 1, and that the time flag 20 is a code indicating that time information is present.Start time waiting process 30, but if the time flag 20 is a code indicating that there is no time information (start time waiting process 3)
0 is not executed, and the input/output start process 31 is executed immediately, but the start time waiting process 30 compares the input/output start time 22 with the current time and waits until the current time becomes larger (later) than the input/output start time 22. Board If the input/output start time 22 is already larger than the current time when starting the start time waiting process 30, even though the input/output start process 31 is executed, the time error processing process 33 is executed as a time error. (Start inputting audio information as digital data from the outside and temporarily storing it in the information transfer means 14 of the control information storage means 10.) If input/output cannot be started, it will be considered an error and input/output abnormality notification 3
Do step 5. Skin where input/output is performed Input/output monitoring process 3
Even if step 2 is performed, in the input/output monitoring process 32, if it becomes impossible to continue human output, an input/output abnormality notification 35 is issued as an error has occurred. In addition, the time flag 20 indicates that there is time information. Compare the input/output end time 23 with the current time. If the current time becomes greater than the input/output end time 23 before the end of input/output, it will be considered as a time error. If the time flag 20 indicates that there is no time information even after the error processing step 32 is performed, the input/output completion notification step 34 is performed if the input/output ends normally.

In the time error processing process, the instruction is re-executed according to the contents of the time error processing flag 24 of the time information storage means 13.
The process branches to processes such as abnormal termination and normal termination, and an input/output start process 31, an input/output abnormality notification 35, and an input/output termination notification 34 are performed next.

As described above, when the input/output process 27 in the audio input/output means 1 is completed, the transfer process 28 is performed.
The host control means 5 checks the transfer status flag 2I of the control command storage means 12 of the control information storage means 10. If the transfer status flag 21 is a code indicating that the input/output process 27 has been completed without error, the audio information temporarily stored in the information transfer means 14 is transferred to the bus means 11. Information transfer means of the control information storage means 7 Then, the transfer state flag 2I of the control instruction storage means 12 of the control information storage means 10 is set as a code that the processing instruction I5 cannot be executed, and the control instruction storage means 12 of the control information storage means 7 is transferred to the control instruction storage means 14. By setting the transfer status flag 21 as a code that can be executed by the processing instruction 15, the input/output process 27 in the storage means 3 can be started. The execution of the input/output process 27 in the audio input/output means 1 is the same as that in the audio input/output means 1 except that the flag 20 indicates that there is no time information. If the input/output process 27 in the means 1 ends abnormally, the operation input process 26 is performed again.

For example, when simultaneously storing audio information from the audio input/output means 1 to the storage means 3 and video information from the video input/output means 2 to the storage means 4, the same applies. Disk magneto-optical disk Any device capable of recording and reproducing, such as semiconductor memory, can be used.Also, audio input/output means 1 and video input/output means 2 simply convert analog information and digital information. Monode L compression/
It may be a device that performs signal processing such as decompression, as long as it can operate according to the contents of the control information storage means 7 to 10. Here, audio information is used as information.
Any information that can be handled as digital data, such as text information, etc. that handles video information (~As described above, according to the first embodiment of the present invention, input/output start, end,
Input/output is executed based on time information that defines processing in the event of an error, etc. △ It is possible to input/output multiple pieces of information synchronously. The purpose of the second embodiment of the present invention is to more strictly synchronize input and output of multiple pieces of information such as video and audio.Figure 7 shows the configuration of the second embodiment of the present invention.

, the storage means 3 and 4, and the timer means 36 are connected;
Fig. 8 is a block diagram showing the configuration of the timer means, which is a bus means for transmitting information such as data. In the second embodiment, the timer control means 38 can be controlled only from the main control means 5.Next, the operation of the second embodiment of the present invention will be explained with reference to the drawings. The general operation ζ of the second embodiment is shown in FIG. 5 as in the first embodiment. The input/output process 27 is also shown in FIG. 6. The control information storage means 7 to lO Parts related to control information in each process of operation may be different.The current time in the start time waiting process 30 and the input/output monitoring process 32, which are not explained in the first embodiment, is acceptable. The operation to be obtained will be explained with reference to the drawings, but Fig. 9 shows the second
3 is a flowchart showing the operation of obtaining the current time in the embodiment of FIG.

First, the timer control means 38 of the timer means 36 can be controlled (time reading and setting) only by the main control means 5. In the waiting step 30, if the current time is to be known, the main control means is inquired about the current time using the bus means 11. When the main control means receives an inquiry about the current time, it reads the time information of the counter means 37 through the bus means 11 and the timer control means 38, and notifies the request source.If there are multiple requests, the time information cannot be read. at once,
As described above, according to the second embodiment of the present invention, it is possible to share one time among the entire device, and the synchronous input/output of multiple pieces of information can be performed accurately. Next, a third embodiment of the present invention will be described with reference to the drawings.

The purpose of the third embodiment is to make it possible to obtain time information more quickly and to reduce the error between the obtained time information and the actual time.
The structure is the same as that of the second embodiment except that the timer control means 38 can be controlled not only by the main control means 5 but also by the audio input/output means 1, the video input/output means 2, and the storage means 3 and 4. The operation of obtaining the current time in the third embodiment of the present invention will also be explained with reference to the drawings.

FIG. 10 is a flowchart showing the operation of obtaining the current time in the third embodiment. .4 also makes an inquiry to the timer control means 38 through the bus means 11. At this time, if there are inquiries at the same time, the timer control means 38 performs arbitration by processing the inquiry with a higher priority and rejecting the inquiry with a lower priority. . The timer control means 38 reads the contents of the counter means 37 and responds to the inquiry through the bus means 11.If the inquiry is rejected, the setting request is made at the same time when setting the remaining time for which another inquiry must be made. When a request is received, the timer control platform 38 rejects a request with a high priority and a request with a low priority. The timer control means 38 updates the time information of the counter means 37 in accordance with the received setting request.

As described above, according to the third embodiment of the present invention, it is possible to share one time among the entire device, and it is possible to know the accurate current time, and to synchronize the input and output of multiple pieces of information. A fourth embodiment of the present invention, which can be carried out more accurately, will now be described with reference to the drawings.

The purpose of the fourth embodiment of the present invention is to more strictly synchronize input/output of multiple information such as video and audio. Fig. 11 is a block diagram showing the configuration of the fourth embodiment of the present invention. Amo Figure 11'''C, 1 is an audio input/output means for processing and inputting/outputting audio information, 2 is a video input/output means for processing and inputting/outputting video information, 3.4 is a storage means for storing digital information, 5 6 is the main control ratio for controlling the audio input/output means 1, the video input/output means 2, and the storage means 3.4. 6 is the operation input means for inputting the operation procedure to the main control means 5. 39 to 43 are time information. A clock line 44 operates as a control line for transmitting a clock signal serving as a reference for updating time of the timer means 39 to 43 and controlling changes in time information.11 is a main control stage 5. , the operation input means 6, the audio input/output means 1, the video input/output means 2, and the storage means 3, 4. 44: Even if only the timer means 39 connected to the main control means 5 can be driven, the operation of the fourth embodiment of the present invention will be explained next. Since the operation for obtaining the time is the same as the second embodiment except for the operation for setting the time, it is appropriate to explain the operation for obtaining the current time and the operation for setting the time. The clock signal for updating the time is the timer means 3.
Although the timer means 39 also updates the time based on this clock signal, the main control means 5, operation input means 6, audio input/output means 1, video input/output means 2, storage means 3 and 4 If you want to know the current time, you can read the time information directly from each of the timer means 39 to 43, but this time information must be read during the time setting operation described later. The main control means 5 uses the timer means 39 to output a predetermined signal for setting the time and a signal indicating time information to the clock line 44 so that the time can be determined. When the signal on the clock line 44 changes from a clock signal to a predetermined signal indicating time setting, the timer means 40 to 43 read the time information to be set from the subsequent time signal and set their own time information. After setting the time information, the signal on the clock line 44 becomes a clock signal again, and each of the timer means 35 updates the time information in synchronization. By performing this time setting in the normal initialization process 25, the same time is shared by the entire device when a large amount of information is output.

As described above, according to the fourth embodiment of the present invention ('L
