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.

design LP,HP,B S digital Butterworth and Chebyshev filter. All array has been specified internally,so user only need to input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,..., ksection and the freq.

基于verilog HDL的自动售货机控制电路设计: 可以对5种不同种类的货物进行自动售货,价格分别为A=1.00,B=1.50,C=1.80,D=3.10,E=5.00 。售货机可以接受1元,5角,1角三种硬币(即有三种输入信号IY,IWJ,IYJ),并且在一个3位7段LED(二位代表元,一位代表角)显示以投入的总钱数，最大9.90元，如果大于该数值，新投入的硬币会退出,选择货物的输入信号Ia,Ib,Ic,Id,Ie和一个放弃信号In,输出指示信号为 Sa, Sb ,Sc ,Sd, Se 分别表示售出相应的货物,同时输出的信号yuan, jiao代表找零,相应每个脉冲代表找零相应的硬币，上述输入和输出信号均是一个固定宽度的脉冲信号。
