Abstract

PURPOSE:To continuously write a talkie data in a talkie storage memory by automatically detecting a head address of each talkie data of the talkie storage memory, storing the data in a 2nd memory and reading the data in the talkie storage memory from a relevant talkie head address at the reception of a talkie transmission command. CONSTITUTION:The transmitter is provided with a 1st memory 8 storing data of plural talkies, a 2nd memory 5 storing a head address of each talkie data of the 1st memory 8, a 3rd memory 7 storing a readout address of the 1st memory 8, a control circuit 3, and selection circuits 4, 6 or the like. Upon the receipt of a talkie transmission command signal, the control circuit 3 controls the selection circuit 4, inputs number of a commanded talkie type to the 2nd memory 5 to read a relevant head address and to control the selection circuit 6 thereby writing the data to the 3rd memory 7. An output of the 3rd memory 7 is a read address of the 1st memory 8 and the talkie data to be read is sent to the outside. Thus, even when the length of data differs remarkably, the talkie storage memories are efficiently used.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a talkie sending device that sends out a plurality of talkies.

[Conventional technology]

Conventionally, this type of talkie sending device has stored data for each talkie by a fixed length from a fixed address on a memory for storing talkies.

[Problem to be solved by the invention]

The above-mentioned conventional talkie sending device is configured to store the data of each talkie by a fixed length from a fixed address on the memory for talkie distribution, so the length of each data of a plurality of talkies is If the data lengths do not differ much, the memory for storing data can be used efficiently, but if the difference in data length is large, the memory for storing data can not be used efficiently. There is a drawback that it is not possible to write a fixed length area of other talkies in the talkie storage memory even if there is free space.

[Means to solve the problem]

The talkie sending device of the present invention is a talkie sending device that sends out a plurality of talkies, and includes: a first storage means for storing data for each of the plurality of talkies; and a data storage area for each of the plurality of talkies of the first storage means. a second storage means for storing the start address of the first storage means; and an address specification means for sequentially specifying the read address of the first storage means; and: at the time of initial setting, the first storage means is sequentially read out via the address specification means to read each talkie data. detects the end of the next address and stores the next address as the start address of the next talkie data in the second storage means, reads out the start address of the corresponding talkie data from the second storage means when the talkie transmission instruction is received, and the address designation means and control means for sequentially reading corresponding talkie data from the first storage means and transmitting the data to the outside.

Further, when storing a silent data pattern in the first storage means and not receiving a talkie transmission instruction, the address of the silent data pattern in the first storage means is selected from the second storage means, and the address of the silent data pattern in the first storage means is selected. It is also possible to adopt a configuration in which the silent data pattern is read out from the storage means and sent to the outside.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The talkie sending device of this embodiment includes a first memory 8 for storing data of a plurality of talkies, and a first memory 8 for storing data of a plurality of talkies.
A second memory 5 that stores the start address of each data of each talkie in the memory 8, a third memory 7 that stores the read address of the first memory 8, a timing creation circuit 1 that creates control timing, and a second A counter 2 that counts the address value of the memory 5, a WiI control circuit 3 that controls the whole, a selection circuit 4.6, an adder circuit 9 that adds "1" to addresses, and a tri-state gate 10. We are prepared.

Next, the operation will be explained.

Data for each of a plurality of talkie types is stored in the first memory 8 in advance, and identification data, for example, data of all bits "O", is stored in the delimiter portion of each talkie data.

At the time of initial setting for turning on the power to the talkie sending device, the control circuit 3 outputs a counter 2 reset signal, and the output data of the counter 2 becomes "O".

Further, the data at address O in the second memory 5 also becomes "O".

At this time, under the control of the control circuit 3, the selection circuit 4 selects the counter 2 side and inputs data "O" as the address of the second memory 5. Similarly, the selection circuit 6 selects the second memory 5 side and inputs the read data "O" as the data of the third memory 7.

The timing generation circuit 1 performs read and write operations for the third memory 7 and generates addresses for the first memory 8. The output data of the first memory 8 is input to the control circuit 3,
If all the bits are not "0", the selection circuit 6 is configured to add "1" to the output data of the third memory 7 in the adder circuit 9 and use it as the address of the first memory 8.
The input selection is switched to the adder circuit 9 side, and the process is repeated until all bits of the output data of the first memory 8 become "O".

When all bits are "0", the control circuit 3 increases the count value of the counter 2 by "1'" and starts the next adder circuit 9.
Select the output of circuit 6. Write to the second memory 5 via the third memory 7 and the tri-state gate 10.

If reading from the first memory 8 is performed for all addresses, at the end, the next address where all bits "O'" have been detected will have been written into the second memory 5 in order. In this way, if data for identifying the talkie type question is used, the start address of each talkie data in the first memory 8 will be written to the address corresponding to the number of the talkie type in the second memory 5. .

After the above operations are completed, when the control circuit 3 receives the talkie sending instruction signal, it controls the selection circuit 4, inputs the number of the talkie type for which sending is instructed to the second memory 5, reads the corresponding start address, and selects the selected circuit. 6 and writes its start address into the third memory 7. The output of the third memory 7 becomes the read address of the first memory 8, and the read data is sent to the outside. The adder circuit 9 adds "1" to the address data in the third memory 7 until data for discrimination between types is detected, and the address data is inputted to the third memory 7 via the selection circuit 6. It is possible to send out a series of talkie data by incrementing the read address by "1".

Note that if a silent data pattern is stored in the first memory 8 and there is no instruction to send out a talkie, by selecting the address of the first memory 8 in which the silent data pattern is stored from the second memory 5. It is possible to send silent data to the outside.

〔Effect of the invention〕

As explained above, the present invention automatically detects the start address of each talkie data in the talkie storage memory of the first storage means at the time of initial setting and stores it in the second storage means, and when the talkie sending instruction is received, 2. By reading out the start address of the corresponding talkie from the storage means and reading the talkie storage memory from that address, it is possible to continuously write the talkie data as much as the capacity allows in the talkie storage memory, and to write various talkie data. If the total time of the talki is kept within the capacity of the talkie storage memory, there is an effect that the time of one talkie can be freely selected within the range.
