不使用乘法器的乘法运算

基于basys2的简单的乒乓球小游戏，通过ise13.4开发，使用语言VHDL，能够通过VGA在显示屏显示，能够实现双人对打，有计分功能。(Simple table tennis game, based on basys2 through ise13.4 development, using VHDL language, can through the VGA display shows, can achieve a double play, scoring function.)

说明：  电网协议信道解交织器设计FPGA实现，适用于PB16的宽带电力线载波通信(Grid protocol channel deinterleaver design FPGA implementation, suitable for PB16 broadband power line carrier communication)

通过 ICAP 回读 FPGA内部state register 的状态值。通过状态机控制ICAP，然后写入命令，读取数据，等待三个周期后出现数据。过程中CSIB和RDWRB有一个时序关系，还需要对ICAP输入命令进行bit swap

针对初学FPGA的人，简单易懂，用notepad++打开可以看到QuartusII里的中文注释，方便学习和开发

运用vhdl硬件描述语言在quartus II开发环境下独立设计与实现了基于精简指令集的五级流水线CPU的设计与实现。该流水CPU包括：取指模块，译码模块，执行模块，访存模块，写回模块，寄存器组模块，控制相关检测模块，Forwarding模块。该CPU在TEC-CA实验平台上运行，并且通过Debugcontroller软件进行单步调试，实验表明，该流水线CPU消除了控制相关、数据相关和结构相关。(Using vhdl hardware description language development environment under quartus II design and implementation of an independent design and implementation of a five-stage pipeline RISC-based CPU' s. The water CPU include: fetch module, decoding module, execution modules, memory access module, the write-back module, the register set of modules, control relevant to the detection module, Forwarding module. The CPU in the TEC-CA experimental platforms, and single-step debugging through Debugcontroller software, experiments show that the pipelined CPU eliminates the control-related, data-related and structurally related.)

VHDL实现SPI功能源代码 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.(SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the )
