45.7420 题目:The 7400-series integrated circuits are a series of digital chips with a few gates each. The 7420 is a chip with two 4-input NAND gates.Create a module with the same functionality as the 7420 chip. It has 8 inputs and 2 outputs. 大白话:7420芯片内部集成了两个4输入与非门,...
out_different: Each bit of this output vector should indicate whether the corresponding input bit is different from its neighbour to the left. For example, out_different[2] should indicate if in[2] is different from in[3]. For this part, treat the vector as wrapping around, so in[3]'s...
out_different[2]should indicate ifin[2]is different fromin[3]. For this part, treat the vector as wrapping around, soin[3]'s neighbour to the left isin[0].

Irreversible gates are the circuits which have an information loss. Losing information in a circuit causes losing power. So reversible gates have a better advantage when compared to irreversible gates. Using Verilog and VHDL we are creating a library of reversible gates such as AND, OR, CNOT, ...

There are several statements in Verilog that have no analog in real hardware, e.g. $display. Consequently, much of the language can not be used to describe hardware. The examples presented here are the classic subset of the language that has a direct mapping to real gates. ...
