坦克游戏的VHDL代码

this is fpga based vhdl coding and report for wavlet based image compression in vhdl

说明：  采用FPGA（现场可编程门序列）编写VHDL语言设计多路同步脉冲发生器，对信号进行分频处理，实现四路信号相位相差T/16和T/8的延迟相位输出，实现的四路脉冲与传统的脉冲同步器不同，它具有高集成度，高通用性，容易调整和高可靠性等特点。(Using FPGA (field programmable gate sequence) to write VHDL language to design multi-channel synchronous pulse generator, to divide the frequency of the signal, to achieve the four-way signal phase difference T / 16 and T / 8 delay phase output, the realization of the four-way pulse is different from the traditional pulse synchronizer, it has the characteristics of high integration, high-throughput, easy adjustment and high reliability.)

这是一个数字时钟的数字逻辑电路，整个工程打包上传，时钟可以计时、校时、整点报时、定时闹钟。使用电路图实现的。在quatarsII里面仿真的并且下载到DE2板上运行过。-This is a digital clock digital logic circuits, the whole project package upload, the clock could be time, school hours, the whole point timekeeping, timing alarm clock. The use of circuit implementation. The quatarsII inside the simulation, and downloaded to the DE2 board to run-off.

此ip核是xvga视频接口控制器，主要针对xilinx公司的开发工具-This ip is nuclear XVGA video interface controller, the main target Xilinx

xilinx FPGA设计需要的DDR2文件，可以应用于实际设计中(xilinx FPGA design needs DDR2 files that can be applied to the actual design)

32位存储器Verilog附带test文件，可以在modulesim仿真 还有加法、减法器，译码器等常用Verilog器件，都附带仿真test。(Memory test with Verilog)

基本功能的cpu，自定义内存内容~了解CPU运作原理~(design of cpu,VHDL environment~)

verilog编写，巧妙的通过计数方式完成了三角波的波形，可直接对da输出。(verilog written, cleverly accomplished by counting the triangular waveform can be output directly to da.)

viterbi译码器的IP核，可以直接编译使用-viterbi decoder IP core, the compiler can directly use
