概述随着数字计算机的高速发展和广泛应用,快速乘法问题日益引起人们的注意。过去,为了加快乘法运算速度,主要采用以下三种方法:组合逻辑、快速加法器和多位并行处理等手段。大规模集成电路的出现,给人们开辟了一条设计快速乘法器的新途径,就是采用廉价的大规模集成片 ROM 器件和以前模似计算机曾用过的“四分之一平方乘法器”技术相结合,而产生的名为“四分之一数字平方乘法器。 Overview With the rapid development and widespread use of digital computers, the issue of rapid multiplication has drawn increasing attention. In the past, in order to speed up multiplication, the following three methods were mainly used: combinatorial logic, fast adder and multi-bit parallel processing. The advent of large scale integrated circuits has opened up a new way for designers to design fast multipliers by using inexpensive large-scale integrated chip ROM devices and the “quarter square multiplier” technology that was used in previous analogue computers The resulting combination, called “Quarter-Digit Square Multiplier.”
