AHB2APB Bridge 的Verilog

基于VHDl的2FSK调制！用的是altera的quartus11软件(Based on VHDl the 2FSK modulation)

该书介绍了英特尔的80x86CPU和一些串行通信芯片，以及汇编语言。(The book introduces the Intel 80x86CPU and some serial communications chip, and assembly language.)

伪随机序列发生器的vhdl算法 设计一个伪随机序列发生器，采用的生成多项式为1+X^3+X^7。要求具有一个RESET端和两个控制端来调整寄存器初值（程序中设定好四种非零初值可选）(m sequence vhdl)

汉明码学习，以（7，4）为例，仿真正常。(Hamming code learning, taking (7, 4) as an example, the simulation is normal.)

说明：  设计一个哈夫曼编码器 要求对一段数据序列进行哈夫曼编码，使得平均码长最短，输出各元素编码和编码后的数据序列。 ① 组成序列的元素是[0-9]这10个数字，每个数字其对应的4位二进制数表示。比如5对应0101，9对应1001。 ② 输入数据序列的长度为256。 ③ 先输出每个元素的编码，然后输出数据序列对应的哈夫曼编码序列。(Designing a Huffman Encoder Huffman coding is required for a data sequence to minimize the average code length and output the coded and coded data sequence of each element. (1) The elements that make up the sequence are the 10 digits [0-9], and each digit is represented by its corresponding 4-bit binary number. For example, 5 corresponds to 0101, 9 corresponds to 1001. (2) The length of the input data sequence is 256. (3) First output the encoding of each element, and then output the Huffman encoding sequence corresponding to the data sequence.)

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

利用verilog实现对SD卡的控制，可以实现对SD卡的读写。(Verilog SD)

97小波_2D_2Level的FPGA实现，适用的97提升小波变换，包含了完整的97小必争变换和反变换

说明：  RISC全部源码，包含仿真文件，使用makefile脚本编写，能通过vcs编译(RISC all source code, including simulation files, using makefile script, can be compiled through VCS)

VHDL语言编程简单实例若干，适合于初学者(VHDL language programming simple example, suitable for beginners)
