基于VHDL的LED显示控制程序

SRAM 读写实验，SRAM存储器的读写操作，Verilog源码有助于提高代码coding能力。使用例程。(SRAM write and read)

用verilog写的，基于查表法实现的LOG10运算器，在Altera FPGA中应用。-It is a verilog design of LOG10 calculation unit, which is based on LUT arithmatic. And it is applicated in Altera FPGA.

高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)
