vhdl,序列信号发生器，发出11101010，可更改为任意序列

五级流水线CPU实现（带Hazard），还没来得及实现Cache求高人指教(pipeline CPU with Hazard)

实现了UART的底层协议，加入了控制器，其波特率可以根据使用进行调整；发送模块、接收模块相互独立，互不影响。(Realization of the underlying protocol UART, joined the controller baud rate can be adjusted according to use transmission module, receiver module are independent of each other.)

根据软件无线电的思想，提出了一种新颖的数字信号处理算法，对QPSK信号的相位进行数字化处理，从而实现对QPSK信号的解调.该算法允许收发两端载波存在频差，用数字锁相实现收发端载波的同步，在频偏较大的情况下，估算频偏的大小，自适应设置环路的带宽，实现较短的捕获时间和较好的信噪性能。整个设计基于XILINX公司的ISE开发平台，并用Virtex-II系列FPGA实现。用FPGA实现调制解调器具有体积小、功耗低、集成度高、可软件升级、扰干扰能力强的特点，符合未来通信技术发展的方向。(According to the idea of software radio, a novel digital signal processing algorithm, the phase of QPSK digital signal processing, enabling the demodulation of QPSK signals. This algorithm allows the sending and receiving ends of the carrier frequency difference exists, using digital phase-locked to achieve synchronization of sending and receiving end of the carrier, in the case of large frequency offset, frequency offset estimation of the size, adaptive set the loop bandwidth to achieve shorter acquisition time and better noise performance. The whole design is based on the company XILINX ISE development platform, and Virtex-II series with the FPGA. FPGA realization of a modem with a small size, low power consumption, high integration, software upgrades available, the characteristics of strong interference interference, in line with the future direction of ICT development.)

对用开发板上开关产生的信息做汉明编码并通过串口发送至电脑(The Hamming code is generated from the switch on the development board and sent to the computer through the serial port.)

本例程位于 VMD642_CPLD目录中。 使用 CPLD 实现辅助译码、LED 指示灯控制、看门狗等各种逻辑控制电路。源程序使 用 Verilog HDL书写，编译开发系统使用 Cypress公司的 Warp 6.3。(This routine is located VMD642_CPLD directory. Using CPLD implementation auxiliary decoding, LED indicator control, watchdog, and other logic control circuitry. Written using Verilog HDL source code, the compiler development system using Cypress' s Warp 6.3.)

关于USB开发的verilog开发程序，非常的全面，学习FPGA开发时用得着。(About USB development verilog development process, very comprehensive, learning FPGA development time worthwhile.)

该源码为几个正弦ROM,已经编译并通过,可以直接下载,不需要,内部含有正弦ROM表,还有ROM的宏模块-the source for several sine ROM, has been compiled and passed, can be directly downloaded, not internal ROM containing sine table, the Acer ROM module

说明：  Vivado是Xilinx最新的FPGA设计工具，支持7系列以后的FPGA及Zynq 7000的开发。与之前的ISE设计套件相比，Vivado可以说是全新设计的。无论从界面、设置、算法，还是从对使用者思路的要求，都是全新的。看在Vivado上，Tcl已经成为唯一支持的脚本，此文件是vivado是tcl命令的集合。(Vivado is Xilinx's latest FPGA design tool that supports development of FPGAs and Zynq 7000s in the 7 series and beyond. Compared with the previous ISE design suite, Vivado can be said that the new design. No matter from the interface, settings, algorithms, or from the user ideas, are new. Look at Vivado, Tcl has become the only supported script, this file is vivado tcl command collection.)
