4点基2按时间抽取的FFT处理器设计

The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The 720-channel source driver has true 6-bit resolution, which (The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data.

滤波器就是对特定的频率或者特定频率以外的频率进行消除的电路，被广泛用于通信系统和信号处理系统中。(Filter is a circuit that eliminates specific frequencies or frequencies other than specific frequencies. It is widely used in communication systems and signal processing systems.)

ADC芯片ADS8329数据采集的verilog代码，已经用在工程中，没问题。(ADC chip ADS8329 data acquisition Verilog code, has been used in the project, no problem.)

Arbiter code for simulation purpose

无需使用任何乘法器乘法运算。乘法是通过使用移位操作，并找出一些乘法创新的想法，无需使用乘数。

十分基础的CCD的测试程序，大家可以下载调试CCD(this is a ccd test chengxu ,it is very good to use ,you can down it )

这一设计实例深入浅出，介绍怎样产生一个Qsys子系统。 您将产生一个含有以下组成的Qsys系统:在Cyclone IV GX收发器入门套件上,设计带嵌入式收发器的Gen1×1硬核IP的 PCI Express IP编译器。 (Qsys system: the Cyclone IV GX Transceiver Starter Kit, designed with embedded transceivers Gen1 × 1 hard IP PCI Express IP compiler.)

16点FFT，简单易理解，适合初学者了解(16 point FFT, simple and easy to understand, suitable for beginners to understand)

基于查找表的DDS的Verilog实现，分为相位累加器模块、ROM模块和顶层DDS模块(Verilog implementation of DDS based on lookup table)

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.)
