基于VHDL语言的CORDIC算法实现，用于计算sin(x),cos(x)等，实测可用(Based on VHDL CORDIC algorithm, used to calculate sin (x), cos (x), etc., the measured available)

verilog 比较基础的教程 呵呵 新手学习学习啊 大家有资料工乡-basis of comparison of the tutorial Verilog Ha ha ah novice learn Rural U.S. Data Works

说明：  以ISE为开发环境，Verilog语言编写程序。功能：FPGA控制 LCD_1602动态显示秒表(In the development environment of ISE, Verilog language is used to write programs. Function: LCD_1602 dynamic display stopwatch controlled by FPGA)

实用的程序代码，希望对大家有用，已经调试通过-Practical program code, in the hope that useful to everybody, has debugging through

用VHDL语言实现数字钟的设计，要求设计实现一个具有带预置数的数字钟，具有显示年月日时分秒的功能。用6个数码管显示时分秒，set按钮产生第一个脉冲时，显示切换年月日，第2个脉冲到来时可预置年份，第3个脉冲到来时可预置月份，依次第4、5、6、7个脉冲到来时分别可预置日期、时、分、秒，第 8个脉冲到来后预置结束，正常工作，显示的是时分秒。Up为高电平时，upclk有脉冲到达时，预置位加1.否则减1。

这个程序是基于等精度测频原理的频率计，用VHDL语言实现，频率测量测量范围1~9999；用4位带小数点数码管显示其频率，并且具有超量程、欠量程提示功能。-This procedure is based on the principle of frequency measurement accuracy, such as the frequency meter, using VHDL language, frequency measurement range 1 ~ 9999 with four decimal places with the frequency of the digital display and has a super-range, less range prompts.
