这是我自己写的4人表决器源码，在xilinx Spartan3E 上已经调试成功，拿出来与大家分享！...

本文研究了SMBus 规范，介绍了典型的基于片上系统（SoC）设计的知识产权核（IP）实现，采用自顶向下 (Top-down)的集成电路设计方法完成了设计，并架构了基于总线功能模型(BFM)的验证平台 完成功能仿真，顺利完成了逻辑综合和时序仿真。FPGA 验证和投片后测试均表明设计具有 良好的性能。(This paper studies the SMBus specification, based on the introduction of the typical system-on-chip (SoC) intellectual property core design (IP) implementation, using top-down (Top-down) of the integrated circuit design methods achieve a design and architecture based on the total Line functional model (BFM) achieve functional verification platform for simulation, successfully completed a logic synthesis and timing simulation. FPGA silicon validation and post-tests show that the design has good performance.)

基于tus5000评估板的VHDL源代码，用于超声波检测，xinlinx提供的(Based on the VHDL source code tus5000 uation board, used in ultrasonic testing, xinlinx provide)

in this code very useful for designing real number concept

Verilog 语言编写 PCI9054 控制器的接口电路，实现 PCI总线到本地 8 位总线的转接控制(The Verilog language writes the interface circuit of the PCI9054 controller to realize the transfer control of the PCI bus to the local 8 bit bus)

说明：  risc 8 by coonan compatible with PIC16C57

一个用Verilog编写的编帧、解帧及码速匹配的程序，相当经典(Verilog prepared with a series of frames, frames and solutions yards speed matching procedures, rather classic!)

说明：  VHDL资料 很不错的！！！！！！！！！！！(VHDL )

该程序是整个OFDM接收机的程序，希望对做这方面的朋友用些帮助，也希望朋友们和我一起探讨OFDM收发信机。(The program is the whole OFDM receiver process, hope to do in this area with some friends to help and also hope that friends and I explore OFDM transceiver.)

2ask调制与解调的源代码，经过测试可用(2ask modulation and demodulation source code is available, tested)
