用c语言实现DCT的快速傅里叶算法，即用16的dsp实现fft的变换-DCT-fast Fourier transform algorithm ，using6 dsp fft of transformation 。

DCT的FPGA实现，用verilog语言把DCT的快速算法即LOEFFLER算法表示出来。-DCT-FPGA, with the verilog language to the fast DCT algorithm, which is LOEFFLER algorithm that out.

The 8x8 discrete cosine transform (DCT) is an efficient, real-valued transform often used in image compression. Special, fast algorithms for the DCT have been developed to accommodate the many arithmetic operations involved in implementing the DC
