VHDL Programing

维特比译码器，调用IP核，软判决输入，开发平台Xilinx Spartan-6系列FPGA(viterbi decoder, using IP core resource, soft decision input,develop platform is Xilinx Spartan-6 series FPGA)

直接数字频率合成器（Direct Digital Frequency Synthesizer：DDFS）的VHDL程序,开发环境是QuartusII,系统时钟为50MHz，由PLL产生DDFS的工作时钟166.67MHz,地址位宽为24位，频率字为20，相位字为10，RAM用于存储查找表，其地址位宽为10，数据位宽为8。-Direct Digital Frequency Synthesizer ( DDFS) of the VHDL program, the development environment is QuartusII, the system clock to 50MHz, the work of DDFS generated by PLL clock 166.67MHz, address bit-width of 24-bit frequency word is 20, phase word for 10, RAM used to store look-up table, its address is 10 bits wide, the data is 8 bits wide.

由于在网上很难下载到EDA技术－窦衡的PPT，所以本人经过学习后做成word，供大家下载。只针对VHDL语言部分和所有的程序。-Because the Internet is difficult to download to EDA technology- Douheng of the PPT, so I made after learning after the word, for all to download. Only for part of the VHDL language and all the procedures.

FPGA设计的四种常用思想与技巧，包括乒乓操作、串并转换、流水线操作、数据接口同步化(FPGA design of the four common ideas and techniques, including the operation of ping-pong, SERDES, pipelining, synchronization of data interface)

ecc椭圆算法RTL,verilog源代码经过验证，用于FPGA或者ASIC(ECC elliptic curve encryption algorithm for Verilog implementation)

数字频率计 数字频率计-Digital frequency meter digital frequency meter

本程式為使用Verilog語言寫控制DRAM的控制模塊, 可以簡易的控制DRAM IC, 本程式已經過系統驗證.(program for the use of the Verilog language to write the control of DRAM control module, be easy to control DRAM IC, the program has been systematically verified.)
