SU385275A1 - DEVICE FOR FORMING CONSTANTS IN DIGITAL COMPUTER MACHINES - Google Patents

Description

one

The invention relates to the area of computing IH technology that can be used in the case of a digital computer isterstrain with the representation of numbers in, about the inferior data system.

It is known a device for forming a constant in a digital computer containing a desilter, a rator, the outputs of which are connected to the inputs of the pulse and the control unit, and a control unit and.

The disadvantages of the known device are large instrumental costs and complexity of the design.

Description: The device is distinguished from the well-known in that it contains a counter, the outputs of which are connected to the inputs of the decoder, and the input is connected to the unit with the right phenomenon, and the lightest element. “NON-AND-NON, -inputs of which 1 are connected not: ny1. To the outputs of the fratra deshi, -a output - to the auxiliary input of the Shifer.

The drawing shows a block diagram of a device for forming constit in a digital computer. .

The device contains a counter D decoder 2, log element 3 "NOT-AND-NOT, encoder 4 and block | control | VLBNIIYA (on the drawing moiKasiaH). The outputs 5-7 of the counter i are connected to the “lO inputs of the cheap | And | fractionor 2, the outputs 8-W. Which are connected to the inputs of the coder 4: and the inputs of the element 3,

output 11 is connected with an additional input 12 of the encoder 4. The counters 13 and 14 are connected to the control unit.

Counter / intended for fixing

5 1M1Tables of constants formation device states. The number of outputs in the counter is determined by the numbers of the triggers needed to represent the required number of device states.

The decoder 2 serves to recognize the c4ieT4HKa states corresponding to the limit states: the sizes of the constants being formed. The number of inputs of a descrambler is determined by the number of decipherable states of the counter;.

; The concept of the decidable state of the counter (it doesn’t follow, think. In real cases, the set of coistants used to solve a certain circle is characterized by the fact that in each of the ionstants a significant number of digits has ONE the same value. Therefore, proceeding from the reflections of a more economical technical implementation of the iKOHcTiaiHT forming devices, it is advisable to "recognize only those values of bits that are in the minority. For example, in the Constants 0.9999..., 984, 0.9999. ..
