Abstract

The invention relates to automation and computing technology and can be used to organize the processing of information reproduced from a code magnetic storage device. The purpose of the invention is to increase the reliability of the device due to the phase synchronization of the bits of the incoming information. The device includes a mode switch I, a switch 2, a memory block 3, a machine word generator 4, a display unit 5, a control unit 6, a query trigger 7. The multichannel measurement information through the switch 2 is fed to the inputs of the memory unit. Each bit of parallel code is inserted into the memory block on the front of the bit signal. In block 3, the information is stored for the time required for the arrival of all code bits from the magnetic tape. This eliminates the temporal mismatch of code bits relative to the clock synchronization signal, which occurs due to the physical transfer of the magnetic heads of the code magnetic storage device. 1 3.p. f-ly, 6 ill.

The structure of information data frame || a is a sequence of information words — parallel binary codes of measured signals and signals, with a code dimension of each word of at least 8 bits and with synchronization of each word code with a TCC signal (clock

data from one of the sources (inputs of the first and second groups) are fed to the input of memory block 3, where they are stored on the trigger register for the time required for all code bits to arrive from the magnetic tape and to transfer the contents of the information word of block 3 to the machine 4 the words. The period of this time is determined by the control unit 6 and is 0.3-0.5 of the TCC arrival period.

TSS is fed to the input of block 6, where it is delayed and fed to the shaper 4 to allow data to be entered using the one-shot 8, and also sets to 1 trigger 7. If I exist in the trigger 7, the computer organizes a data input cycle from the shaper outputs 4, after which, by the response signal, the Input resets the trigger 7 to O. Upon the arrival of the next TCC signal, the data input cycle is repeated. By add. sync signal), arriving at a signal delayed separately in block 6, f

The device can be effectively used in combination with coded magnetic storage devices. When the device is working, information usually comes from the information inputs of the first group, previously registered on the tape drive and, therefore, reproducible from it, and the information input from the second 1) Oh group usually receives the same information as the recording on the magnet - ovuyu tape drive. These inputs provide data to the device at the same time as they are recorded by a code magnetic storage device, and the information inputs of the first group after they are recorded.
