这是一个基于NIOSII的俄罗斯方块游戏设计，是基于FPGA的，利用流模式DMA传输实现游戏。(This is a box based on the Russian NIOSII game design, is based on the FPGA, and the use of streaming mode DMA transfer realize the game.)

verilog编写的QPSK发射机的ＦＰＧＡ部分，已经过验证，完全达到要求。调制矢量误差４％(QPSK transmitter verilog prepared by the FPGA portion, has been proven, fully meet the requirements. Modulation vector error of 4 )

单相混合有源电力滤波器的设计与控制，在matlab中的仿真模型，功能效果很好。(The design and control of single-phase hybrid active power filter in matlab simulation model, the function works well.)

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.)
