Verilog HDL: Magnitude
For a vector (a,b), the magnitude representation is the following:
A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

基于verilog HDL的自動售貨機(jī)控制電路設(shè)計(jì):
可以對5種不同種類的貨物進(jìn)行自動售貨,價格分別為A=1.00,B=1.50,C=1.80,D=3.10,E=5.00 。售貨機(jī)可以接受1元,5角,1角三種硬幣(即有三種輸入信號IY,IWJ,IYJ),并且在一個3位7段LED(二位代表元,一位代表角)顯示以投入的總錢數(shù)，最大9.90元，如果大于該數(shù)值，新投入的硬幣會退出,選擇貨物的輸入信號Ia,Ib,Ic,Id,Ie和一個放棄信號In,輸出指示信號為 Sa, Sb ,Sc ,Sd, Se 分別表示售出相應(yīng)的貨物,同時輸出的信號yuan, jiao代表找零,相應(yīng)每個脈沖代表找零相應(yīng)的硬幣，上述輸入和輸出信號均是一個固定寬度的脈沖信號。
