SU450369A1 - Counting module - Google Patents

Description

The invention relates to the field of pulsed technology.

A counting module is known, containing n annular shift registers and a transfer valve, the input bus of the module being connected to one of the inputs of the transfer valve and to the input of shifting the ring registers.

The purpose of the invention is to increase the standardization level when building binary counters. For this, the counting module additionally contains n equivalence schemes, one input of which is connected to the output of the ring shift register, the other with the module tuning bus, and the output to the input of the nepetioca valve.

FIG. 1 shows the block diagram of the proposed module; in fig. Figure 2 shows an example of encoding the state of the counting decade.

The counting module contains the transfer valve 1 of the type “I, n logic elements 2 of the type“ equivalence, semiconductor reversing ring registers 3, transfer tires 4 and reverse 5, write tires 6, bus 7, and output buses of module 8 , n tuning tires 9 and output tire 10.

The operation of the module is considered at, / g 4.

Before starting work in register 3; (2, 3, 4) record the sequence of numbers in the 1st column (see Fig. 2). For time 2

The cisi on the inhibit bus 7 provides a signal breaking the feedbacks of the ring registers. When the decade is operating in the summation mode, the bus 5 sends a signal that opens the circuits

shift of the registers to the right, and the input of the 9g setting is the signal corresponding to the last digit recorded in register 3 ;. In this case, the tires 9i-9, s give the signals "O," O, "1," 1, respectively.

Upon receipt of the counted pulses on the bus 4 is the shift of the sequences recorded in the ring registers. As a consequence, a code appears on the output buses of the module, corresponding to the number of emulsified ones. The transfer pulse on the output bus 10 appears only with the arrival of the 10th pulse, since the code on the module tuning buses coincides with the code representing the state of the 9th decade.

The delays required for reliable operation of the module are made due to a two-stage construction of shift registers on the potential elements.

In the subtraction mode, the decade works in a similar way, but on the reverse 5 bus, a signal is given that opens the left shift values, and on the tuning buses, the signals corresponding to the first digits of the sequences under-registers.
