DES加密算法的VHDL实现,采用流水线技术实现-The VHDL implement of DES encrypt algorithmic

this is vhdl behavorial model of a dct chip at an algorithmic level

This document is in two parts. The first part takes an unbiased view of VHDL and Verilog by comparing their similarities and contrasting their differences. The second part contains a worked example of a model that computes the Greatest Common Divisor

各种乘法器，不同算法类型的，适用于不同情况。(Various multipliers, different algorithmic types, are applied to different situations.)
