Description: 此程序用C语言写的DCT变换。DCT变换 DCT变换的全称是离散余弦变换(Discrete Cosine Transform)，是指将一组光强数据转换成频率数据，以便得知强度变化的情形。若对高频的数据做些修饰，再转回原来形式的数据时，显然与原始数据有些差异，但是人类的眼睛却是不容易辨认出来。-DCT transform of this program written in C language. The full name of the DCT DCT transform is discrete cosine transform (Discrete Cosine the Transform), refers to a set of intensity data into frequency data, in order to know the intensity change of circumstances. Do high-frequency data modification, and then back to the original form of data, it is clear there are some differences with the original data, but the human eye is not easily recognizable

Description: 用FPGA实现的JPEG压缩器，可以直接使用，内含完整文档说明-This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second at the maximum resolution 352x288 (on XC2V1000-4 @ 40 MHz). IMAGE RESOLUTION IS LIMITED TO 352x288. It takes an RGB input (row-wise) and outputs to a memory the compressed JPEG image with headers. A testbench has been made that takes a bitmap image from your computer and writes a compressed JPEG file by simulating the code. In order to be able to run the project you must first generate the RAM/ROM cores and the DCT2D core with Xilinx CoreGen. The configuration values are listed at the bottom of the file compressor.vhd. If you run into any problems downloading the files from the cvs please check that you are downloading them in binary form.
