Description

one

The invention relates to computing technology, namely, devices for recording information in the operational memory, and can be used in the coordinate cults of the input information.

The aim of the invention is to improve the speed of the device.

The drawing shows a block diagram of the device.

The device for zatsisi information in the RAM contains block 1 synchronization, block 2 input information, converter 3 codes, group 4 registers, consisting of registers 5, 6, 7, register 8, switch 9, decoder 10, distributor 1I pulses, block 12 elements OR, counter 13, comparison unit 14, device outputs 15-18, device inputs 19, 20.

The device works as follows.

When the button 2 is pressed, the signals are generated at the corresponding outputs of the decoder 10, which leads to the initial installation of the distributor 11, and then the registers 5-8. In registers 5, 6, the code of the starting address of any array of memory cells is written, and

A zone number code is written to register 5, and a cell number code in a zone is written to register 6. The registers 7, 8 write the code of the end address of the array, and the register of the register 7 records the code of the final address of the array, and the register of the zone number is written to register 7, and the register of the cell number in the zone is written to register 8. The address bytes from registers 5-8 pass to the output of the device through switch 9, having input 19 for external control. The counter 13 at the beginning of each cycle of operation of the device is set to O. The code in counter 13 from registers 5, 6 is recorded in each cycle of operation of the device by a signal generated in block 1. Counter 13 operates in the counting mode under the influence of external signals at input 20 generated by transmitting each information byte via interface lines from the coordinate information input panel. At the moment of transfer of the last information byte, the code at the output of the counter 13 becomes equal to the code recorded in registers 7 and 8, as a result of which block 14 generates a signal for the transmission of information bytes.
