FIR滤波器：自定滤波器的类型（低通，高通或带通）、设计指标（通带截止频率、通带波纹、阻带截止频率、阻带衰减） 1、根据指标选择合适的窗函数，用窗口设计法设计符合指标的FIR滤波器；并验证其性能是否满足预定指标。 (FIR filters: Custom filter types (low pass, high pass or band-pass), design specifications (passband cutoff frequency, passband ripple, stopband cutoff frequency, stopband attenuation) 1, according to indicators choose the right window function, using the window design method of FIR filter designed to meet the targets and verify that its performance meets the set targets.)

主要通过频率分配 实现不同时间的变化 达到呼吸一闪一闪的效果

5604FPGA驱动，能显示数字（5604里面为4个595）(5604 FPGA driver, able to display digital (5604 contains 4 595))

用verilog hdl语言编写的fpga与片外sram 的读写控制(With the verilog hdl language fpga sram chip with read and write control)

说明：   基于VHDL语言数字秒表设计,在FPGA实验平台下开发(Digital stopwatch design based on VHDL, FPGA experimental platform under development)

在xilinx的ml507板子上用的ICAP功能 配置存储器 这里边包含了控制程序 以及配置ICAP寄存器的程序 就是完整的通过串口控制FPGA多重配置的程序 用verilog实现的(how to configure the ICAP)

本文描述了fpga中的亚稳态时如何产生的，以及如何计算亚稳态的平均无故障时间。对了解亚稳态有帮助。-This paper describes the sub-fpga how the steady state, as well as how to calculate the metastable MTBF. The understanding of metastable helpful.
