- 要求采用快速进位链(Look Ahead)设计一个21位加法器; 2) 采用结构化的设计方法,所有加法器均采用步骤1)的21位加法器; 3) 在加法器阵列中加入流水线结构(Pipelinc),输入连续送数,输出连续出结果,流水线填满后每拍输出一个结果; -1) requires the use of fast carry chain (Look Ahead) design a 21-bit adder 2) the use of structured design metho
8 bit, bit by bit procesing unit
- This module does an bit by bit sum, 2 complement,or,and,xor,and not operation of two 8 bit numbers (not and 2 compliment its just 1 number) It has two shift registers that feed your numbers to the procesing unit with an external load/shift signal and
Johnaon_counter
- 本设计为六位约翰逊(Johnson)计数器,首先给大家介绍一下什么是约翰逊计数器,它又称扭环计数器,是一种用n位触发器来表示2n个状态的计数器。它与环形计数器不同,后者用n位触发器仅可表示n个状态。2~n进制计数器(n为触发器的个数)有2~n个状态。若以6位二进制计数器为例,它可表示64个状态。但由于8421码每组代码之间可能有二位或二位以上的二进制代码发生改变,这在计数器中特别是异步计数器中就有可能产生错误的译码信号,从而造成永久性的错误。而约翰逊计数器的状态表中,相邻两组代码只可能有一位二进
