multi_booth
基于quartus的布斯乘法器的verilog 实现。布斯乘法算法是计算机中一种利用数的2的补码形式来计算乘法的算法。该算法由安德鲁·唐纳德·布斯于1950 年发明，当时他在伦敦大学伯克贝克学院做晶体学研究。布斯曾使用过台式计算器，由于用这种计算器来做移位计算比加法快，他发明了该算法来加快计算速度。(The verilog codes of booth multiplier based on quartus. Booth multiplication algorithm is a computer algorithm using the complement form of number 2 to calculate the multiplication. The algorithm was invented in 1950 by Andrew Donald booth, who was working on crystallography at birkbeck college, university of London. Booth used a desktop calculator, and because it was faster to do shifts than to add, he invented the algorithm to speed up the calculations.)
