Abstract

PURPOSE:To decrease the converting time of numerical value for a decimal- binary converting circuit, by using hardware circuits including a storage circuit, a binary adder circuit, a digit designating circuit, a latch circuit, etc. and eliminating a converting process using a software. CONSTITUTION:A decimal-binary converting circuit includes the 1st latch circuit 1 which stores an N-digit decimal number, a digit designating circuit which designates each digit, and a multiplexer circut 3 having a data input D and a control input C that deliver each digit value given from the circuits 2 and 1. The output of the circuit 1 is fed to the data input of the circuit 3, and the output of the circuit 2 is fed to the input C of the circuit 3. Furthermore, a decimal number is converted into a binary number and stored in a storage circut 4, and the outputs of the circuits 2 and 3 are fed to the circuit 4. The output converted into a binary number given from the circuit 4 is fed to the input A of one side of a binary adder circut 5. The output of the circut 5 is temporarily latched at the 2nd latch circuit 6. The output of the circuit 6 is fed to the input B of the other side of the circuit 5. Thus the time can be decreased for the decimal- binary converting process without using any software.
