针对于Virtex5FPGA的DDR2读写测试的完整工程

说明：  FPGA实现四位数与四位数乘法，有仿真波形，合理利用FPGA资源(Four-digit and four-digit multiplication is realized by using FPGA. It has simulation waveform and makes rational use of the resources of the FPGA.)

用于fpga学习，共同分享学习经验和交流学习心得-For fpga to learn, to share learning experiences and the exchange of learning

VHDL实用教程，详细介绍VHDL语法、开发环境、应用实例等。。。(VHDL course)

double edfe trigger d latch

基于FPGA的电子密码锁设计-已在开发板上成功运行，通过老师检验。(FPGA based electronic password lock design- has been successfully developed on the development board, through the teacher inspection.)

详细讲述TURBO码的FPGA实现原理，可作参考，不是码源(A detailed account of the FPGA implementation of principle of the TURBO code can be used as reference, not source code)

verilog实现rtc文档，可用于实现RTC。(verilog realize rtc document can be used to implement the RTC.)

VHDL实现PI调节的算法。内部使用整数计算，避开了浮点数的运算。仿真结果正确-VHDL realize PI regulator algorithm. Internal use integer calculations to avoid the floating point arithmetic. The simulation results correctly

turbo码在LTE中的实现，并在fpga中得到了实现(turbo code in LTE implementations, and have been achieved in fpga)

这个是专门用在ALtera第二代PLD MAXII上的16位微处理器IP核，文档齐全-this is the ALtera devoted second-generation PLD MAXII on the 16-bit microprocessor IP core, complete documentation
