cordic_atan
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.)

EDAshiyan2s
通过上翻键和下翻键来设置方波信号正负脉冲宽度，利用一排流水灯来显示按键的次数，通过观察流水灯亮的盏数确定占空比（按一次上翻键亮一盏灯，流水灯全亮时占空比调到了最高或者是最低状态，按一次下翻键灭一盏灯，流水灯全灭时占空比调到了最低或者是最高状态）。(Duty cycle of LED lights and adjustable oscilloscope display code)
