售货机-VHDL语言-已调试通过 真的很好用哦~适合一切学习EDA的初学者，能够让你轻松度过EDA课！~(Vending machine-VHDL language- has been really good with debugging by Oh ~ EDA for all beginners to learn, to let you easily through the EDA class! ~)

说明：  使用XILINX公司提供的板子里面的FFT的IP核，很好用(XILINX board provided the use inside the FFT of the IP core, useful)

Verilog经典实例.包括洗衣机红路灯、兹自动方麦基、等式子可用(Classic examples of Verilog. Including red street lights for washing machines, ZAM, equation availability)

自己用verilog编写的urisc程序，调试成功，压缩包里有仿真图像，值得学习参考。(Written in verilog urisc program debugging, simulation image compression bag, worth learning reference.)

Top module name : SHIFTER (File name : SHIFTER.v) 2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT. 3. Output pins: OUT [15:0]. 4. Input signals generated from test pattern are latched in one cycle and are synchronized at clock rising edge. 5. The SHIFT signal describes the shift number. The shift range is 0 to 15. 6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it shifts input data to left. 7. When the signal SIGN is high, the input data is a signed number and it shifts with sign extension. However, the input data is an unsigned number if the signal SIGN is low. 8. You can only use following gates in Table I and need to include the delay information (Tplh, Tphl) in your design.

CORDIC(Coordinate Rotation Digital Computer)算法即坐标旋转数字计算方法。 CORDIC算法,能够通过平移和累加快速实现基础的数学函数,包括三角函数,开方,指数,对数,平方根等函数。(CORDIC (Coordinate Rotation Digital Computer) algorithm for the coordinate rotation digital calculation. CORDIC algorithm can be achieved through the rapid translation and accumulation based on mathematical functions, including trigonometric, square root, exponential, logarithmic, square root and other functions.)
