Description

one

The invention of computer technology and can be used, for example, in systems for measuring the statistical distributions of random greatness — in multi-analyzers of imulses.

A multichannel counting device is known, which contains a control circuit connected to read-write elements of the information carrier and write generators, as well as a circuit for adding a unit.

The proposed device differs from the known one in that it contains a parity feature trigger, the outputs of which are connected to the parity feature recording control circuits, the zero output is associated with the write control circuit in the first bit position, the single output - with the write control circuit in the remaining bits positions, and the output is connected to the element of reading - the record of the parity feature.

This simplifies the device.

The drawing shows a diagram of the proposed device.

The accumulated information in each channel is recorded in the medium / information of the periodic storage device. In the information carrier, for example, sections are allocated for each channel with the help of synchronizing pulses, and inside the channel -

2

bit positions for writing binary digits “O and“ 1. All bits of a code written in a particular channel are read by a group of read-write elements 2. Readable

Codes occur at the outputs of the 3 read elements of the read - write. The inputs of the 4 read-write elements are connected to the outputs of the 5 "O and" 1 generator, with which the binary code is changed in the channel selected by the steering circuit (not shown in the drawing).

The device contains a trigger 6 parity feature, which is used to write into it the parity feature read from the selected

channel; parity attribute control circuit 7 connected to unit 8 and zero 9 parity feature trigger outputs and generator 5 inputs serving the position to which the attribute is written

parity; the write control circuit 10 in the first bit position connected to the zero output 9 of the parity indication trigger 6 and the read / write elements 2 and the write generators 5 serving the first bit position; charts // control of the rest of the bit positions connected to the unit output 8 of the trigger 6 of the parity attribute and the read / write elements and the write generators 5 serving all the bit positions.

at the very beginning of the operation of the device, all channels are free, i.e., at all times, the correct positions of the parity signs of all channels are recorded. All the channels in turn, each once per period of the storage device, are selected by the control circuit (not shown in the drawing). When a particular channel is selected, the information contained in it is read.

The code for the selected channel is read out in several cycles in groups of a certain number of bits. During the first clock cycle, the read / write element 2 reads the parity flag. The read - write element is intended to serve only the position of the parity attribute. The read parity features enter the trigger 6 of the parity feature, the binary digits from the first bit position go to the write control / f control in the first bit position, and the binary digits from all bit positions go to the write control / control in the rest of the bit position. x

If, before selecting the next channel, the control circuit gives the command to add a unit to it, the device works as follows.

Immediately after reading the parity attribute and writing it to the trigger 6, the control circuit 7 for writing the parity attribute starts the corresponding write generator 5 connected to it and the reverse value of the parity attribute is written to the same place of the information carrier 1, i.e. is equal to zero, the record generator 1 is started and a unit is written in its place, and if the read parity is equal to one, the record generator O is started and written to the same place of the information carrier zero. The flip-flop 6- saves the read parity attribute.

If the read parity feature is zero, immediately after reading a binary digit ("O or" 1) from the first bit position and entering it into the circuit 10 in the first bit position, the latter starts the corresponding generator 5 connected to it and as a result the reverse value of the read binary digit is recorded. This completes the process of adding one to the selected channel.

If the read parity feature is equal to one, the circuit 11 in the remaining bit positions is working, in which binary digits from all bit positions of the selected channel are received.

The circuit 11 in the remaining bit positions selects the bit position following the position containing the first unit, and using generators 5 connected to it, changes the binary digit in the selected bit position to the opposite. Such an order of operation of the circuit // in the remaining bit positions has one exception. If the reading is done before the last bit position, since all bit positions contain zeros, it is changed to the reverse binary digit in the last bit position. In this case, when the channel is full, the count in it is cyclically repeated.
