Abstract

PURPOSE:To share a system memory and decrease the number of memories, and to obtain a speech recording and reproducing device compact and low in the cost by interposing a first-in first-out memory between a speech recording and reproducing LSI and a system control means. CONSTITUTION:A speech inputted by a speech input means 5 is converted into a speech signal, which is converted by a speech data converting means 26 into speech data. Then the first-in first-out memory FIFO 22 for sound recording is stored with the speech data in order, and a memory detecting means 24 for sound recording detects at least one of the memory used capacity and memory remaining capacity of the FIFO 22 and outputs the detected value. A system control part judges whether or not the detected value exceeds a specific value, and stores the speech data out the FIFO 22 in order and stores them in a speech data storage means when the specific value is exceeded. Therefore, this speech data storage means and the system memory part of the device are used to eliminate the need for a memory dedicated to speech data, and the system memory can be shared as a speech data memory, thereby decreasing the number of memories.

The command output from the system control unit 1 is input to the voice recording / reproducing LSI 26 via the system bus 8 or the I / O port unit 7 to control the voice recording / reproducing LSI 26. In the following description, the operation via the I / O port unit 7 will be described, but the same applies to the case where the system control unit 1 controls via the system bus 8.

When recording voice data, first, the system controller 1 inputs a command for setting the bit rate of the transfer rate of voice data to the voice recording / reproducing LSI 26.
Then, after inputting a recording standby state setting command, a start command is input to start recording. When recording is started, the voice recording / playback LSI 26 compresses and modulates the voice message input from the microphone 5 and outputs it as voice data. The output timing of the audio data differs depending on the type of memory connectable to the audio recording / playback LSI 26, and is generally SRAM or DRAM type. In the following description, the case of DRAM connection type will be described.

When the voice recording / reproducing LSI 26 outputs the voice data at a predetermined timing, the voice recording / reproducing LSI interface section 25 synchronizes with the output, and the recording FIF.
While writing to the O memory unit 22, it outputs a count-up clock to the recording FIFO data counting unit 24. Next, the counter value of the recording FIFO data counting section 24 is incremented in synchronization with the count-up clock from the voice recording / reproducing FIFO interface section 20. At this time, the system control unit 1 regularly reads the counter value of the recording FIFO data counting unit 24 via the system control unit interface unit 20, and when the counter value exceeds a predetermined threshold value, the system control unit interface unit 20. FIFO for recording via
The audio data is read from the memory section 22 and transferred to a predetermined storage section of the system memory section 2. Here, the system control unit 1 periodically reads the counter value of the recording FIFO data counting unit 24 to determine whether or not the threshold value is exceeded.
The data counting unit 24 may generate an interrupt signal to notify the system control unit 1.

Next, the system control unit interface unit 20 reads the audio data from the recording FIFO memory unit 22 in synchronization with the data reading timing of the system control unit 1 and outputs it to the system control unit 1 and at the same time, the recording FIFO. The countdown clock is output to the data counting unit 24. Next, the counter value of the recording FIFO data counting unit 24 is decremented in synchronization with the countdown clock from the system control unit interface unit 20. Then similarly for recording FIFO
The recording FIF is determined by the counter value of the data count unit 24.
One of the memory usage amount and the memory remaining amount of the O memory unit 22 is regularly monitored, and the same operation is repeated until the end of recording while synchronizing so that the recording FIFO memory unit 22 does not overflow. . Recording is ended by inputting a stop command from the system control unit 1 to the voice recording / playback LSI 26, but is also ended when the maximum accessible address of the voice recording / playback LSI 26 is reached.

When reproducing audio data, first,
The system control unit interface unit 20 synchronizes the audio data stored in the predetermined storage unit of the system memory unit 2 at the time of recording with the audio data write timing of the reproduction FIFO memory unit 21 of the system control unit 1 by the system control unit interface unit 20.
The audio data is written in the FO memory unit 21, and the system control unit interface unit 20 sets the reproduction FIFO.
The count-up clock is output to the data counting unit 23. The counter value of the reproduction FIFO data counting unit 23 is incremented in synchronization with the count-up clock from the system control unit interface unit 20.
Similarly, audio data is transferred from the system memory unit 2 to the reproduction FIFO memory unit 21 until the counter value of the reproduction FIFO data count unit 23 reaches a predetermined maximum set value.

When the memory of the reproduction FIFO memory section 21 becomes full, the voice recording / reproducing LSI 26 causes the voice recording / reproducing L
Audio data is read from the SI interface unit 25 at a predetermined timing. The voice recording / playback LSI interface unit 25 reads the voice data from the playback FIFO memory unit 21 in synchronization with the read timing of the voice recording / playback LSI 26 to the voice recording / playback LSI interface unit 25, and the voice recording / playback LSI 26.
And outputs a countdown clock to the reproduction FIFO data counting unit 23.

Then, in synchronization with the countdown clock from the voice recording / reproducing LSI interface section 25, the counter value of the reproducing FIFO data counting section 23 is decremented. At this time, the system control unit 1 periodically reads out the counter value of the reproduction FIFO data counting unit 23, and when the counter value falls below a predetermined threshold value, the system memory unit 2 via the system control unit interface unit 20. FI for playback of audio data stored in
The audio data is written in the FO memory unit 21 and is controlled so that the audio data stored in the reproduction FIFO memory unit 21 is not lost. Although the system control unit 1 periodically reads the counter value of the reproduction FIFO data counting unit 23 to determine whether the threshold value is exceeded,
The reproduction FIFO data counting unit 23 may generate an interrupt signal and notify the system control unit 1 when the value falls below the threshold value.

Similarly, either the memory usage amount or the remaining memory amount of the reproduction FIFO memory unit 21 is periodically monitored by the counter value of the reproduction FIFO data counting unit 23, and the reproduction FIFO memory unit 21 is also monitored. The same operation is repeated until the end of reproduction while synchronizing so that the memory 21 is not empty. The reproduction is ended by inputting a stop command from the system control unit 1 to the voice recording / reproducing LSI.

It is sent to the system memory unit 2.

On the other hand, at the time of reproduction, the audio data output from the system memory unit 2 is transferred to the reproduction FIFO memory unit 21.
In accordance with the counter value from the reproduction FIFO data counting unit 23, the reproduction FIFO memory unit 21 is stored so as not to overflow, and then the voice recording / reproducing LSI
26, the audio data is temporarily transmitted to the FI for reproduction.
