JPH05119789A - Speech storage device by controlling line-by-line buffer memory - Google Patents

Abstract

PURPOSE:To eliminate the wait time for data transfer due to the in-use state of a buffer memory and to improve the throughput by independently controlling data transfer between a speech process part and the buffer memory, and the buffer memory and a storage part. CONSTITUTION:When a main control part 5 sends a sound recording indication to a storage control part 4, the storage control part 4 transfers the data of a line M from the speech process part 2 to the buffer memory 7 of the line. After the transfer, a track number is written and while the data of the line M are transferred from the buffer memory 7 to the storage part 3, the data of a line N are transferred from the speech process part 2 to the buffer memory 7 of the line; and it is confirmed that the data transfer from the buffer memory 7 of the line M to the storage part 3 and the data transfer from the speech process part 2 of the line N to the buffer memory 7 are completed and then data transfer is performed from the buffer memory 7 of the line N to the storage part 3. Consequently, the wait time due to the in-use state of the buffer memory is eliminated and the need to control next track numbers by use and nonuse states and by lines is eliminated.

It has a buffer memory 7 used as a relay memory.

Next, the operation of recording / reproducing a voice message will be described.

Each time there is a recording instruction from the main control unit, the audio data is transferred from the audio processing unit to the buffer memory, and after the transfer is completed, the next track number and the previous track number are added to the message data, and the message data is transferred. Transfer to the storage unit. By repeating this process, the voice data is connected by a bidirectional chain of track units, and the voice data is recorded.

Also, each time a reproduction instruction is given from the main control unit, message data is transferred from the storage unit to the buffer memory in track units, and the next track and previous track numbers are deleted from the message data on the buffer memory to perform voice processing. The audio data is transferred to the audio processing unit, the next track number is managed for each line on the control memory, and the audio data is sequentially transferred to the audio processing unit by tracing the chain each time there is an instruction for the reproduction, thereby performing the reproduction processing. ..

[0006]

In the conventional voice storage device, when there is a recording instruction from a plurality of lines, the voice processing unit of another line is used until the data transfer from the buffer memory of one line to the storage unit is completed. It is necessary to wait for the data transfer from the buffer memory to the buffer memory, and when there is a playback instruction from multiple lines, from the storage unit of the other line until the data transfer from the buffer memory of one line to the audio processing unit is completed. It is necessary to wait for the data transfer to the buffer memory.

During the reproduction process, when the data transfer from the storage unit to the buffer memory on any line is completed, the next track number on the buffer memory is moved to the control memory in preparation for the next reproduction instruction, and is managed for each line. There is a need.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a voice storage device which improves the processing capability by eliminating the waiting time for data transfer due to the use of the buffer memory when recording / reproducing a voice message.

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a voice storage device of the present invention, and FIG. 2 is a block diagram of a conventional voice storage device.

FIGS. 3 and 4 are sequence diagrams when a message is recorded and reproduced by the voice storage device of the present invention, and FIGS. 5 and 6 are message recording and reproduction by the conventional voice storage device. It is a sequence diagram when performing.

A case where message recording is simultaneously performed from the line M and the line N will be described.

When the main control unit gives a recording instruction to the storage control unit, the storage control unit transfers the data of the line M from the voice processing unit to the buffer memory of the corresponding line. After the transfer,
The next / previous track number is written, and the data of the line M is transferred from the buffer memory to the storage unit. At the same time, the data of the line N is transferred from the voice processing unit to the buffer memory of the corresponding line, and the buffer memory of the line M is transferred to the storage unit. After confirming that the data transfer of the line N and the data transfer from the voice processing unit of the line N to the buffer memory are completed, the data transfer from the buffer memory of the line N to the storage unit is performed. The recording process is executed by repeating the above process.

Next, the case where the message is reproduced simultaneously from the line M and the line N will be described.

When the main control unit issues a reproduction instruction to the storage control unit, the storage control unit transfers the data of the buffer memory line M of the corresponding line from the storage unit. After the transfer is completed, the data of the line M is transferred from the buffer memory to the voice processing unit, and at the same time, the data of the line N is transferred from the storage unit to the buffer memory of the relevant line, and the data is transferred from the buffer memory of the line M to the voice processing unit. , And confirming that the data transfer from the storage unit of the line N to the buffer memory is completed, the data transfer from the buffer memory of the line N to the voice processing unit is performed. When there is a reproduction instruction again, the next track number shown on the buffer memory of the corresponding line is designated and the data in the storage section is transferred to the buffer memory. The reproduction process is executed by repeating the above process.

As described above, the data transfer between the voice processing unit and the buffer memory, and the data transfer between the buffer memory and the storage unit are independently controlled, and the recording / recording is performed while simultaneously processing the plurality of lines.
