GMSK
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.)

Static RAM is a tube composed of MOS flip
静态RAM是由MOS管组成的触发器电路,每个触发器可以存放1位信息。只要不掉电,所储存的信息就不会丢失。因此,静态RAM工作稳定,不要外加刷新新电路,使用方便。但一般SRAM的每一个触发器是由6个晶体管组成,SRAM芯片的集成度不会太高,目前较常用的有6116(2K×8位),6264(8K×8位)和62256(32K×8位)。6264RAM有8192个存储单元,每个单元为8位字长。-Static RAM is a tube composed of MOS flip-flop circuit, each flip-flop can store one message. Long as it does not brown-out, the stored information will not be lost. Therefore, the static stability in the work RAM, do not refresh plus the new circuit and easy to use. But generally each SRAM trigger is composed of six transistors, SRAM chip integration will not be too high, there are currently more commonly used 6116 (2K × 8 bit), 6264 (8K × 8 bit) and 62256 (32K × 8 bits). 6264RAM have 8192 storage units, each for 8-bit word length.

基于VHDL的点阵控制
1、固定红色显示一个汉字或图形,显示亮度4 级可调,用一个btn 按钮实现亮度调节,亮度变化视觉效果要尽量明显。2、用从红到绿 8 级渐变色显示一个固定汉字或图形。3、分别用单字循环显示、左右滚动显示、上下滚动显示三种显示方式单色显示四个汉字或图形,显示过程中,显示方式用一个btn 按键进行切换。4、显示的图形或汉字要尽量饱满美观。
