this is a Multiplier and Accumulate (MAC). written in VHDL

此程序为串行通信程序,采用verilog语言编写的,经过仿真验证已经通过.-This procedure for the serial communication procedures, the use of Verilog language, after simulation has been adopted.

用verilog写的4*4小键盘按键检测程序。本工程已经编译好。可以直接在Atera DE1 Fpga开发板上运行-Written using Verilog 4* 4 keypad keys detection procedures. The project has been compiled. Directly in the development of Atera DE1 Fpga board run

用verilog写的CORDIC算法实现，很适合做超越函数的运算。通常用于实现正弦乘法，或者坐标变换。-The cordic arithmetic implemented by verilog is adapted to exceed function.It is usually used to implement sine multiplication or coordinate tuansform.

关于语音通信信道调制的程序代码，是论文的仿真程序(About voice communication channel modulation code, the authors of the paper simulation program)

一个简单的微处理器的实现，能够进行几种常见的操作，对于熟悉计算机的工作原理很有帮助，并且附有详细的设计报告和设计思路。在word文档最后给出了源代码。-a simple microprocessor to achieve, for several common to the operation of the computer for those familiar with the working principle helpful, and with the detailed design reports and design ideas. The word is the final document source code.

说明：  数字钟通过verilog实现，并且支持Modelsim仿真(The digital clock is implemented by Verilog and supports Modelsim simulation)

说明：  用verilog语言实现计算反正切函数，在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程，基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真，并取其中间的I和Q支路做为verilog文件的输入，并将其借条输出与MATLAB实际解调输出作比较。 鉴相器的设计基于CORDIC算法，其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值，并不需要绝对的值，所以并没有给予加权，需要的同学可以自己加上。(Calculated using verilog language arc tangent function, the software radio demodulation PM/FM is particularly used frequently. From the archive is modelsim project, based on 6.5c, inside the PM contains a complete demodulation process of wave generation and simulation matlab file, and whichever is the middle of the I and Q branch verilog file as input, and its IOU demodulated output and actual output of MATLAB for comparison. Phase detector design is based on CORDIC algorithm, its accuracy depends on the iteration depth. As the practical application of engineering demodulated atan value only and does not need absolute value, and there is no weight given to the need of the students can add their own.)
