基于FPGA的QPSK调制解调

FAST HADAMARD TRANSFORM VERILOG FOR IMAGE PROCESSING

32位乘以32位乘法器，由datapath 和控制中心组成，输出64位结果(32bits by 32 bits multiplier )

说明：  基于fpga的spi通信测试 可与stm32进行spi通信测试(SPI communication test based on FPGA can test SPI communication with stm32)

可直接用于zedboard上的串口通信，利用zynq7000的pl部分实现一个简单的UART串口通信(Can be used directly on the zedboard serial communication, the use of zynq7000 PL part of the realization of a simple UART serial communication)

本模块适合所有红外接收端，使用时请注意修改地址码，要接收的就是识别用户码，代码里有标注，谢谢大家的支持！

说明：  有限状态机 rtl code 和 TB验证环境(Finite state machine RTL code and TB verification environment)

LATTICE FPGA FIFO 程序例程，工程详细，全部源代码上传 (LATTICE FPGA FIFO routine, detailed engineering, all source code uploaded)

使用两个8点FFT完成64-point FFT(64-point FFT)

说明：  自己设计的一个其人投票系统，对于VHDL初学者可以参考下(One of their own design their human voting system, for VHDL beginners can refer to the following)

adder_array的设计。加法器阵列设计，顶层模块，四步流水，21位(adder_array the design. The adder array design, top-level module, four-step pipeline, 21)
