运算器是微处理机的中心操作部件,也是逻辑设计重要的着眼点。本文首先论述了运算器的逻辑设计原则,导出设计依据;然后按进展顺序介绍四种设计方案。
The computing unit is the central operating unit of the microprocessor and is also an important point of focus for logic design. This article first discusses the logic design principle of the computing device, derives the design basis; then introduces the four kinds of design schemes in the order of progress.
