说明：  使用FPGA测量频率大小，并且在数码管上进行显示(Frequency measurement using FPGA and display on digital tube)

1024 点得快速傅里叶变换算法 FPGA in verilog(1024 point FFT on a FPGA written in verilog)

SRAM读写测试，每秒进行一次单字节SRAM读写，使用chipscope观察时序波形(SRAM read and write test, a single byte SRAM read and write every second, using chipscope to observe the timing waveform)

说明：  对MAX5250芯片进行控制，实现DA转换输出。(Controlling MAX5250 Chip)

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.)
