[VHDL-FPGA-Verilog] music

Description: 设计并调试好一个能产生”梁祝”曲子的音乐发生器，并用EDA实验开发系统（拟采用的实验芯片的型号可选Altera的MAX7000系列的 EPM7128 CPLD ，FLEX10K系列的EPF10K10LC84-3 FPGA， ACEX1K系列的 EP1K30 FPGA，Xinlinx 的XC9500系列的XC95108 CPLD，Lattice的ispLSI1000系列的1032E CPLD）进行硬件验证。设计思路根据系统提供的时钟源引入一个12MHZ时钟的基准频率，对其进行各种分频系数的分频，产生符合某一音乐的频率，然后再引入4HZ的时钟为音乐的节拍控制，最后通过扬声器放出来。 -Design and debug a good one can produce The Butterfly Lovers piece of music generator, and the development of EDA experimental system (to be used in models of experimental chip with optional Altera s MAX7000 series EPM7128 CPLD, FLEX10K series EPF10K10LC84-3 FPGA, ACEX1K Series The EP1K30 FPGA, Xinlinx the XC9500 series XC95108 CPLD, Lattice s ispLSI1000 series 1032E CPLD) for hardware verification. Design according to the system clock source provided by the introduction of a benchmark 12Mhz clock frequency and its various sub-sub-band frequency coefficients, resulting in consistent with the frequency of a particular music, and then the introduction of 4Hz clock control for the music beats, and finally through Loudspeakers released.

[Software Engineering] FPGA_4FFT

Description: 针对高速数字信号处理的要求,提出用FPGA 实现基- 4FFT 算法,并对其整体结构、蝶形单元进行了分析. 采用蝶算单元输入并行结构和同址运算,能同时提供蝶形运算所需的4 个操作数,具有最大的数据并行性,能提高处理速度按照旋转因子存放规则,蝶形运算所需的3 个旋转因子地址相同,且寻址方式简单输出采取与输入相似的存储器运算单元同时采用3 个乘法的复数运算算法来实现.-In accordance with the requirements of high speed digital signal processing , the algorithmof radix O4 implemented with FPGA and the integrated architecture and butterfly unit are analyzed. With butterfly u2 nit input which is designed by parallel structure and the same address calculation , four operation codes the butterfly unit needs can be provided simultaneously to have the most data parallel and improve the speed of calculation. According to the rotation parameters memory regulation , the addresses of three rotation parame2 ters of butterfly unit are the same with simple style of address generation and similar input and output memo2 ries. The operating unit adopted is implemented by three complex calculation algorithm of multiplication si2 multaneously.
