SU1088133A1 - Counting device - Google Patents

Abstract

The COUNT DEVICE contains a counter whose discharge outputs are connected to the first inputs of the corresponding totalizer bits, the outputs of which are connected to the outputs of the device, characterized in that, in order to extend the functionality, the second inputs of the totalizer bits are combined with the first inputs of the same bits adder, and the input transfer of the first bit is connected to the input of the counter.

Sn The invention relates to a pulse technique and can be used in devices for counting the number of pulses with double precision. Known counting device containing pulse counters, the inputs of which are connected to the inputs of the device l. A disadvantage of this device is its limited functionality. The closest to the invention to the technical essence is a counting device containing a counter, the outputs of the bits of which are connected to the first inputs of the corresponding totalizer bits, the outputs of which are the outputs of device 2. The known device also does not have sufficient functionality because it does not allow counting pulses with double precision. The aim of the invention is to expand the functionality. The goal is achieved in that a counting device containing a counter, the discharge outputs of which are connected to the first inputs of the corresponding bits of the adder, the outputs of which I are connected to the outputs of the device, the second inputs of the bits of the adder are combined with the first inputs of the same bits of the adder, and input transfer of the first bit is connected to the input of the counter. The drawing shows a block diagram of the counting device. The counting device contains a counter 1, the counting input 2 of which is connected to the counting input of the counting device, the reset input of which is connected to the reset input of the counter, each 4th output of the counter is connected to the first and second inputs of the i -th weight of the adder 3, the transfer input of the first discharge The PD of the adder 3 is connected to the counting input 2 of the counting device, and the outputs 4 of the adder 3 are the outputs of the counting device. The device works as follows. If it is necessary to set the zero state to the reset input, before starting work, a pulse is applied, set. returning the counting device to the zero state. In counting mode, the code on the counter outputs is increased by +1 with the arrival of each subsequent pulse, and the code on the outputs A of the counting device is equal to twice the code value on the outputs of the counter. Moreover, for the duration of the input pulse, a unit in the low order is added to the code value at the outputs 4 of the counting device. Thus, in the proposed device, the functionality of the counter is expanded, which makes it possible to use it more effectively in measuring and computing equipment.
