基于FPGA分布式算法FIR滤波器verilog代码
(本人 小论文 代码,通过验证)
本文提出一种新的FIR滤波器FPGA实现方法。讨论了分布式算法原理,并提出了基于分布式算法FIR滤波器的实现方法。通过改进型分布式算法结构减少硬件资源消耗,用流水线技术提高运算速度,采用分割查找表方法减小存储规模,并在Matlab和Modelsim仿真平台得到验证。
为了节省FPGA逻辑资源、提高系统速度,设计中引入了分布式算法实现有限脉冲响应滤波器(Finite Impulse Response, FIR)。由于FIR滤波器在实现上主要是完成乘累加MAC的功能,采用传统MAC算法设计FIR滤波器将消耗大量硬件资源。而采用分布式算法 (Distributed Arithmetic, DA),将MAC运算转化为查找表(Look-Up-Table, LUT)输出,不仅能在硬件规模上得到改善,而且更易通过实现流水线设计来提高速度。因此本文采用分布式算法设计一个可配置的FIR滤波器,并以31阶的低通FIR滤波器为例说明分布式算法滤波器结构。( FPGA verilog )

三态以太网verilog代码
10_100_1000 Mbps tri-mode ethernet MAC implements a MAC controller conforming to IEEE 802.3 specification. It is designed using less than 2000 LCs/LEs to implement full function. It will use inferred PADs to reduce technology dependancies. The whole project will be finished in TEN weeks inluding verilog coding,RTL level verification.
A GUI configuration interface,created by tcl/tk script language,is convenient for configuring optional modules,FiFo depth and verifcation parameters. Furthermore,a verifcation system was designed with tcl/tk user interface,by which the stimulus can be generated automatically and the output packets can be verified with CRC-32 checksum.

traffic_lights
交通灯控制器控制红(r)、绿(g)、黄(y)三种不同颜色的交通灯,这三种不同颜色灯的亮、灭分别由三个定时器(timer1、timer2、timer3)控制;
当某个定时器工作时,它所控制的交通灯亮,直到设定的定时时间到(该定时器状态由’0’变’1’),交通灯跳转到另一种状态;
clk是脉冲控制端(图中未标出);reset是异步复位端,复位状态为红色交通灯亮;
输出端r、g、y分别表示三种颜色交通灯的亮、灭状态。
( traffic light controller control red (R), green (g), yellow (y) three different colors of traffic lights, three different colors of bright lights, off by three timer (Timer1, Timer2, Timer3 ) control When a timer work, it controls the traffic lights, until the set timing (the timer status ' 0 ' for ' 1' ), traffic lights Jump to another state clk is the pulse control terminal (not shown) reset is asynchronous reset terminal, the reset state for the red traffic lights output terminal r, g, y represent the three colors of traffic lights bright, the off state.)
