Description

31501277

The invention relates to digital computing and is intended to convert codes from one number system to another.

The purpose of the invention is to expand the class of problems to be solved by providing the possibility of converting tricative numbers.

The drawing shows a functional converter circuit for n-bit numbers (n - 11), with the most significant bit being a significant bit.

The converter contains discharge inputs of 1 converter, a group of summing tetrads (2-1) - (2-3), a group of summing pentads (2-4) - (2-6), one-bit totalizers 3, transfer performances 4 summing tetrads and suming peace pentad, encoders 5, tetrad outputs 6 of the converter, outputs 7 of the transfer of the encoders 3.

The relationship between Bxoj: tHbiMH and the output codes of the encoder 5 is mapped to 25 in the table.

With one bit number representation in binary code, the high bit has weight, and the additional decimal number code is -1024 at 30 representation in three decimal places, the 2000 is 1024- 976, so the proposed converter for the case of converting numbers presented in code-, 5, equivalent weight equivalents of multi-way single-digit adders of sunstable pentads contain one

in binary bit, the addition of the weight of the sign bit, i.e. the numbers 976. ..M When converting positive. There is no correction in the numbers, since the sign bit is zero, the converter circuit operates in accordance with the description of the converter of the Prototype,

The Converter operates as follows.

Upon receipt of the binary 1 converter on the bit inputs t (ode “1.1110101001, which corresponds to 1, 1 to the inputs with weights 2, 2, 2 2, 2, 2 and O, the remaining inputs, to the outputs of summing pentad ( 2-4) after the end of the transition process, the value of the code 10000 appears. In accordance with the table, the information on the outputs of the decoder 5 is formed by the code 001. Thus.

common tetrade code from output 6 of the converter with a weight of 10 cooTseTCTByet 0011. At the outputs of the transfer 7 of the encoder 5, in accordance with the table, the value of the code 011 is formed.

Similarly, the outputs of the summing pentad (2-5), in accordance with the wiring diagram, the code value 010101 appears. At the information outputs of the encoder 5, the code 000 is formed, and at the outputs 7 of the transfer of the encoder 5 - code 010. The total code of the tetrad weighing 10 corresponds to 0001.

At the outputs of the summing pentad (2-6), code 010011 appears. At the information outputs of the encoder 5, a code 100 is formed. A common tetrad code of weight 101 corresponds to 1001. At the output 7 of the transfer of the encoder and 5, a code 001 is generated. The code of the sign tetrad weighing 10 corresponds to 0001.

As a result of the conversion, on decade 6 transducers, a binary-decimal additional code 0001 1001 0001 0011 is obtained, corresponding to binary code 1.111010100К
