here is realized simple FIFO stack in vhdl. very simple example, but very help...

this is an peak detection alguritm,in this matlab code u can clean base line noise to have clear ECG signal

目前最新的OVL库，里面是标准的ASSERTION模块，支持VHDL刚Verilog，最近在做AXI协议验证的时候用到，分享下(The latest OVL(open verification library),including all standard module of assertions(VHDL and Verilog). It can be used into AXI Protocl Verification. Just share with you guys.)

用VHDL语言实现的图像传感器TCD132D的时序驱动代码,时序精准!-VHDL language with the image sensor TCD132D realize the timing-driven code, timing accurate!

多功能卡的源代码，verilog编写，用于多功能的数据接收-verilog code of mutiple function card

This tutorial explains how to communicate with IO devices on the DE2 Board and how to deal with interrupts using C and the Altera Monitor Program. Two example programs are given that diplay the state of the toggle switches on the red LEDs. The fi rst program uses the programmed I/O approach and the second program uses interrupts.-This tutorial explains how to communicate with IO devices on the DE2 Board and how to deal with interrupts using C and the Altera Monitor Program.

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。
