DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information storage device, and more particularly to an information storage device for voice response using a magnetic bubble memory chip that can read information at a desired basic voice time length.

In a time division multiple response type voice response device, all voice information is read from the information storage device, all voice data is given to the voice editing section for each basic time length of voice, and the voice editing section selects the voice information necessary for the response. do.

When applying a conventional information storage device using a magnetic bubble memory chip to such a voice response device, the basic time length is fixed by the capacity of the magnetic bubble memory chip, making it impossible to set the desired basic time length. The drawback was that I couldn't do it. FIG. 1 shows a block diagram of a conventional information storage device of this type.

In the figure, reference numeral 1 denotes a magnetic bubble unit that uses a magia-minor-loop system and stores audio information. Reference numeral 2 denotes a magnetic bubble unit control circuit that controls bubble driving, reading and writing of the magnetic bubble unit 1, and is roughly divided into a clock pulse generation circuit 3 and a magnetic bubble reading and writing control circuit 4.

Figure 2 shows a 64Kb magnetic bubble memory chip (minor loop number: 132, minor loop bit number: 5) using the major minor loop method used in the magnetic bubble unit 1 of Figure 1.

FIG. 3 is a time chart when audio information is read from the magnetic bubble memory chip shown in FIG.
12-2, . . . , 21-535 are data blocks output from the magnetic bubble unit 1.

In order to increase the information read speed, bit insertion control and phase control are used. In this case, the number of clocks for one data block length (the number of rotation periods of the magnetic bubble driving magnetic field) is expressed by the following equation. Here, 132 is the number of minor loops 13.

2 is a coefficient because the information on the mager loop 12 is stored at a ratio of 1 bit to 2 bits long, so twice the number of clocks is required, and 4 is an empty bit on the mager loop, so the output information requires 4 clocks. This means that a gap can be created.

Therefore, from the magnetic bubble unit 1 in FIG.
Data block 21 is output every 8 clocks, and in order to output all the audio information, it takes 268 clocks x 53 clocks.
5=143380 clocks (2) Required.

This is the time when the rotating magnetic field is 100KHz,
This is the basic duration of the audio.

By the way, when the information storage device as shown in FIG. 1 is used as a voice response device, it is desirable to set the basic time length to 1 degree from the viewpoint of naturalness of the response voice. Therefore, the formula (3
) It is necessary to further shorten the basic time length of 1.4338 seconds. However, the conventional information storage device using magnetic bubbles shown in FIG. 1 has a drawback in that it is not possible to obtain a desired basic audio time length. The present invention solves the drawback that the time to read out the total information in the information storage device, that is, the basic time length of audio, is fixed by the capacity of the magnetic bubble memory chip. By providing a circuit for setting the coil drive start signal and a rotating magnetic control circuit for sending out the coil drive start signal and the coil stop signal, it is possible to freely select the effective number of bits on the minor loop as necessary, thereby obtaining the desired basic time length. The drawings will be explained in detail below.

FIG. 4 is a block diagram of one embodiment of the present invention. In the figure,
The magnetic bubble unit 1 includes a magnetic bubble storage module 34.
, a coil drive circuit 35, a chip drive circuit 36, and a read amplification detection circuit 37. The read amplification detection circuit 37 is connected to the data conversion circuit 23 through an audio read data line 31. As explained in FIG. 2, the memory chip used in the magnetic bubble storage module 34 has a number of minor loops of 132, a number of minor loop bits of 536b, and a number of major loop bits of 534b. The magnetic bubble unit control circuit 22 is roughly divided into a clock pulse generation circuit 3, a magnetic bubble read/write control circuit 24, a rotating magnetic field control circuit 25, and a timing setting circuit 26. The magnetic bubble read/write control circuit 24 includes a minor address counter 38, a minor address register 39, a minor address coincidence detection circuit 40, a major address counter 41, a chip drive control circuit 42,
It consists of an instruction decoder 43. 28 is a coil drive signal line,
29 is a magnetic bubble reading signal line, and 30 is a timing signal line.

33 is a minor address counter line, 44 is a magnetic bubble activation signal line, and the address line 8, magnetic bubble control command line 9, audio data line 32, etc. are the same as in FIG.

FIG. 5 is a time chart of information corresponding to the embodiment of the present invention shown in FIG.
This shows a case where 28 bits are used as effective bits. In FIG. 5, 45-1, 45-2,...
. . , 45-528 is the data block of audio readout information on the audio readout data line 31, 46 is the time length for transferring the magnetic bubble on the major loop onto the minor loop, and 47 is the time length for transferring the magnetic bubble at the start time. The time required to return to the bit position, 48 is the stop time of the magnetic bubble, and 49, 50, 51, 52 are audio data blocks on the audio data line 32. Next, I will explain the operation of Figure A. The timing setting circuit 26 receives the clock from the clock pulse generation circuit 3 and sends various timing signals required by the magnetic bubble unit 1 and the magnetic bubble unit control circuit 22 to the signal line 30. The period of the required timing signal is set in advance.

By applying a minor address start signal from the outside through the address signal line 8 to the minor address register 39 of the magnetic bubble read/write control circuit 24, the minor address register 39 is initialized. The rotating magnetic field control circuit 25 receives the timing signal from the timing setting circuit 26, sends a minor address counter start signal to the minor address counter 38 via the signal line 33, starts the minor address counter, and simultaneously starts the coil drive. Signal and coil drive signal to signal line 2
8 to the coil drive circuit 35 of the magnetic bubble unit 1 to drive the coil. In this way, the operation of the magnetic bubble storage module 34 is started, and then, when the minor address coincidence detection circuit 40 detects a coincidence between the output of the minor address counter 38 and the output of the minor address register 39, the major address counter 41 is started. Then, the magnetic bubble unit 1 is connected from the chip drive control circuit 42 via the magnetic bubble read/write control signal line 29.
A transfer out signal is sent to the major loop, and the magnetic bubble at address 0 on the minor loop is transferred onto the major loop. Further, the chip drive control circuit 42 controls the chip drive circuit 36 and the read amplification detection circuit 37 based on the output of the major address counter 41, and controls the magnetic bubble storage module 3.
4 and sends it to the data conversion circuit 23. When the transfer out signal is transmitted, the minor address register 39 is updated by the address line 8 in preparation for the next match detection with the minor address counter 38.

In this way, the magnetic bubble read/write control circuit 24 repeatedly sends a transfer out signal to the magnetic bubble unit 1 via the magnetic bubble read/write control line 29 every 268 clocks of the timing signal. Further, the magnetic bubble read/write control circuit 24 repeatedly transmits a transfer signal to the magnetic bubble unit 1 via the magnetic bubble read/write control line 29 every 535 clocks, and returns the magnetic bubbles transferred onto the major loop onto the minor loop. These transfer-out signals and transfer-in signals are repeated 528 times (because 528 bits on the minor loop are used as valid bits) for each basic audio time length (for example, 1.32 seconds) set in advance by the timing setting circuit 26. As a result, data blocks 45-1 to 45-528 are sent to the data conversion circuit 23, as shown in FIG. 5a. After repeating transfer-out and transfer-in 528 times, the rotating magnetic field control circuit 25 sends a minor address counter stop signal to the minor address counter 38 and a coil drive stop signal to the coil drive circuit 35 via the coil drive signal line 28. The operation of the minor address counter 38 and the coil drive circuit 35 is temporarily stopped. Thereafter, the minor address register 39 is initialized again, and the rotating magnetic field control circuit 25 sends out a minor address counter start signal, a coil drive start signal, etc. to the set basic audio time length of 1.32S. , the above operation will be repeated. The data conversion circuit 23 converts the audio information sent from the magnetic bubble unit 1 into a desired audio information format (for example, the audio information shown in FIG. 5b) and sends it to the outside. FIG. 5b shows how information for one frame=10 msec of each word is output in a time-division manner. In the above explanation,
The number of effective bits on the minor loop was set to 528, but this can be freely selected as required as long as it is less than the maximum number of bits on the minor loop, 535. Also, the magnetic bubble stop time 48 in FIG. 5a can be expanded or contracted as needed. Therefore, for example, the basic time length can be set to 0.8 seconds. As an embodiment of the present invention, FIG. 4 shows a case in which both the timing setting circuit 26 and the rotating magnetic field control circuit 25 are included, but a configuration in which either one of these is excluded is also possible.

Further, in the embodiment shown in FIG. 4, the magnetic bubble unit control circuit 22 controls only one magnetic bubble unit 1, but the magnetic bubble unit control circuit 22 also controls a plurality of magnetic bubble units arranged in parallel. It is clear from the above explanation that a configuration in which this is the case is also possible. As explained above, the information storage device of the present invention has the advantage that a desired basic audio time length can be set without being limited by the capacity of the magnetic bubble memory chip used.

Therefore, the present invention should be used in a time-division multiple response type voice response device that reads out all voice information from the information storage device for each basic time length of voice and sends it to the voice editing section, where the voice editing section selects the necessary voice. For example, since it is possible to design using a basic time length that provides good naturalness, a response message with good naturalness can be obtained.
