本文利用全加器、半加器，利用进位保留的思想，在前向割集中加入四级流水实现了乘法器的设计，提高乘法器的运算速度，并且介绍了乘法器的VHDL的程序编写过程以及代码，并给出了仿真波形-In this paper, the use of the full adder, half adder using carry-save ideological forward cutset added four water to achieve a multiplier design, to improve the speed of operation of the multiplier, and the multiplier in VHDL programming as well as the code given simulation waveforms
