上海外滩看到的最大的LED显示屏的内核源代码，主要是完成视频信号的远距离传输的编解码与接口转换...

A ROM to build a squaring circuit

说明：  传感器是一种检测装置，能感受到被测量的信息，并能将感受到的信息，按一定规律变换成为电信号或其他所需形式的信息输出，以满足信息的传输、处理、存储、显示、记录和控制等要求(Sensor is a kind of detection device, which can sense the measured information and transform it into electrical signal or other required information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.)

里面包含了三段代码，主要是用matlab产生高斯随机信号以及高斯白噪声和色噪声，然后计算其数字特征及对这些信号进行频谱分析和功率谱分析，里面还有关于低通滤波器的设计的简单说明(Which contains three sections of code using matlab Gaussian random signals and white Gaussian noise and color noise, and then to calculate the numerical characteristics and spectral analysis and power spectral analysis of these signals, there is also the low-pass filter design BRIEF DESCRIPTION OF)

A BLIF to VHDL converter (51K compressed tar, with SunOS, Solaris, and Linux binaries. Source code (C++) included).

4位的booth算法加法器，对计算机组成原理的学习有帮助，verilog语言编写(4-bit adder booth algorithm, the learning of computer organization help, verilog language)

分频计数器是指对信号进行分频处理的计数器，分频分偶数和奇数分频两种。VHDL主要用于描述 数字系统的结构，行为，功能和接口。除了含有许多具有硬件特征的语句外，VHDL的语言形式、描述风格以及语法是十分类似于一般的 计算机高级语言。VHDL的程序结构特点是将一项工程设计，或称设计实体（可以是一个元件，一个电路模块或一个系统）分成外部（或称可视部分,及端口)和内部（或称不可视部分），既涉及实体的内部功能和算法完成部分。在对一个设计实体定义了外部界面后，一旦其内部开发完成后，其他的设计就可以直接调用这个实体。这种将设计实体分成内外部分的概念是VHDL 系统设计的基本点。

把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。 (The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

VHDL与源代码包-and VHDL source code

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure.

说明：  一个使用VHDL进行正弦波信号产生的历程，非常有用。(A sine wave signal generator using VHDL for the course, very useful.)
