这是一个计算机组成原理综合性实验：设计8位cpu。该cpu是8bit的代码，包含有4个寄存器，一个存储器，还有alu以及控制器。一共可以实现16条指令。(This is a computer composition principle of comprehensive experiment: Design 8 cpu. The cpu is 8bit code contains four registers, a memory, as well as alu and controllers. A total of 16 instructions can be achieved.)

ARM处理器的IP核，用verilog编写的，对处理器和相关的CPU架构知识有很大帮助。(ARM processor IP core, written in verilog processor and CPU architecture knowledge.)

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.)
