Icache设计

说明：  adrv9009的测试平台的测试脚本，适合新人参考(Adrv9009 test platform test script, suitable for new reference)

In this design, it is assumed that a buffer sized as 1024x8 bits provides main data including scale factors and Huffman code bits to Huffman decoder. Also, it is assumed that a memory with 1024x8 bits is ready for each component to write or read the output or input 576 frequency lines.(This folder contains three directories: Huffman, IMDCT and Filterbank, each of them includes all the VHDL source codes of the component.)

FPGA实现SPI接口的从机功能，接收和发送全双工运行，接收到的数据以八位LED灯显示(FPGA to achieve the SPI interface the machine function, receive and send full-duplex operation, the received data to eight LED lights)

用Verilog语言实现的FPGA UART独立收发模块 思路简单，代码简洁。在Lattice LFE3EA VERSA开发板上验证通过,编译器Lattice Diamond. 功能：串口收到数据后立即回传，此后每一秒串口数据+1再发送。(Using Verilog language independent of FPGA UART transceiver idea is simple, concise code. Development board in Lattice LFE3EA VERSA verified by the compiler Lattice Diamond. Features: Serial data is received immediately after the return, then every second serial port and then send the data+ 1.)

实现dsp与fpga的emif的verilog异步实现，可实现异步读写以及相应功能模块控制，文件中包含仿真后的波形图形以及仿真测试程序，运行环境quartus ii11.0，仿真环境mmodelsim se 6.5d(Achieve dsp and fpga verilog asynchronous implementation of the emif, enabling asynchronous reading and writing as well as the corresponding function module control, the document contains graphics, and after the simulation waveform simulation testing procedures, operating environment quartus ii11.0, simulation environment mmodelsim se 6.5d)

Decoder using Miller method for UHF reader

i2c配置SAA7113，非常有用的程序，做视频采集类必看(i2c configure SAA7113)

本代码主要功能是PPM解码，采用Verilog语言，通过移位寄存器和组合电路实现解码。(The main function of this code is PPM decoding.)

哈希算法FPGA实现代码，采用MD5算法，并给出了仿真波形。(MD5 hashing algorithm for FPGA implementation code)

用VERILOG实现一个被除数为8位、除数为4位的高效除法器(With VERILOG implement a dividend for the 8-bit, 4-bit effective divisor divider)
