SPI的verilog代码的可编程时钟

掌握SDRAM数据读写、刷新、初始化以及FPGA串口收发时序，熟练FIFO IP核的生成和调用。(Master SDRAM data read and write, refresh, initialization and the timing of sending and receiving of the serial port of the FPGA, skilled in the generation and invocation of the FIFO IP core.)

这是一个很实用的，很实用的，关于软件的使用，大家可以来看看。-This is a very practical, very practical, with regard to the use of software, everyone can come and see.

这是VHDL中计数器的代码。

书名：LDPC原理与应用。是国内第一本介绍用LDPC编、译码基本原理及应用技术的一本书。对用 vhdl 或verilog实现硬件编程LDPC的人开发无线通信是很好的资料(Title: LDPC Principles and Applications. Is the first book describes using LDPC Encoding and Decoding the basic principles and application of technology, a book. Right to use vhdl or verilog hardware programming LDPC people to achieve development of wireless communications is a very good information)

在matlab仿真的基础上，用maxplus2实现等波纹法的程序代码(In matlab simulation, based on the use of such corrugated maxplus2 realize law code)

设计一简易数字频率计，其基本要求是： 1)测量频率范围0～999999Hz； 2)最大读数999999HZ,闸门信号的采样时间为1s；. 3)被测信号可以是正弦波、三角波和方波； 4)显示方式为6位十进制数显示； 5）具有超过量程报警功能。 5)输入信号最大幅值可扩展。 6）测量误差小于+-0.1%。 7)完成全部设计后，可使用EWB进行仿真，检测试验设计电路的正确性。(The basic requirements of designing a simple digital frequency meter are: 1) The measuring frequency range is 0-999999 Hz. 2) The maximum reading is 999999HZ, and the sampling time of gate signal is 1 s. 3) The measured signal can be sine wave, triangle wave and square wave. 4) The display mode is 6-bit decimal number display. 5) It has alarm function beyond range. 5) The maximum amplitude of input signal can be expanded. 6) The measurement error is less than +0.1%. 7) After completing all the design, EWB can be used to simulate and test the correctness of the circuit.)

Modelsim简明使用手册，十分适合新手使用-Modelsim concise user manual is very suitable for novice to use

说明：  VHDL语言写的SRAM控制程序，在开发板上验证过。(Written in VHDL SRAM control procedures, the development board verified.)

提供了利用 GPIF 对 FX2LP 与同步 FIFO CY7C4625-15AC 之间的接口进行设计的源代码(Provides for the use of GPIF FX2LP and synchronization FIFO CY7C4625-15AC to design the interface between the source code)

本书共由三篇组成。其中第一篇由第1~3章组成，介绍PCI总线的基础知识。第二篇 由第4~13章组成，介绍PCIExpress总线的相关概念。第二篇的内容以第一篇为基础。(This book comprises a total of three components. The first chapter from the first 1-3 chapters, introduces the basics of the PCI bus. Second by the first 4 to 13 chapters, introduces concepts related PCIExpress bus. The contents of the first to second basis.)
