说明：  移位相加8位硬件乘法器电路设计 乘法器是数字系统中的基本逻辑器件，在很多应用中都会出现如各种滤波器的设计、矩阵的运算等。本实验设计一个通用的8位乘法器。
(Shift combined 8-bit hardware multiplier multiplier circuit design is a digital system in the basic logic devices, in many applications will emerge, and such a variety of filter design, such as matrix calculations. The experimental design of a generic 8-bit multiplier.)
