本文介绍一种以二一十进制的加、减计数器、移位寄存器等时序电路为基础,辅以寄存器和与非门,用时序逻辑尖现加、减、乘、除快速数字运算的线路,可以单次运算,也可以连续运算,线路简单,运行可靠。本文介绍的方法,可以比较简单的构成一台数字输入数字输出的专用运算设备,解决科研、生产、生活中提出的大量的、重复的、简单的运算问题,例如:求和、差、平均值、平方和乘(除)以常系数等。也可以在测量仪器或控制设备中做为中间数字运算环节采用。
This article describes a binary system based on sequential addition and subtraction counters, shift registers and other sequential circuits, complemented by registers and NAND gates, and with fast digital operations using sequential logic points to add, subtract, multiply and divide lines , Can be a single operation, but also continuous operation, the line is simple, reliable operation. This article describes the method can be relatively simple to form a digital input digital output dedicated computing device to solve the scientific research, production, life, a large number of, repeated, simple arithmetic problems, such as: sum, difference, average , Square and multiply (except) constant coefficient. It can also be used as an intermediate digital calculation in measuring instruments or control equipment.
