LED流水灯例程

基于查找表的DDS的Verilog实现，分为相位累加器模块、ROM模块和顶层DDS模块(Verilog implementation of DDS based on lookup table)

FPGA，用VHDL语言产生可调的PWM波(FPGA, VHDL language adjustable PWM wave)

基于fpga的coms摄像头 扫描，参考文献，(Fpga based on the coms camera scan, reference literature,)

1、PC和寄存器组使用时钟触发。 2、指令存储器和数据存储器存储单元宽度一律使用8位，即一个字节的存储单位。 3、控制器部分可以考虑用控制信号真值表方法（有共性部分）与用case语句方法逐个产生各指令其它控制信号相配合，注意：信号必须与状态配合。。当然，还可以用其它方法，自己考虑。 4、试用的汇编程序，而且必须包含所要求的所有指令。Slt、sltu指令必须检查两种情况：“小于”和“大于等于”；beq、bne指令必须检查两种情况：“等”和“不等”。这段汇编程序必须尽量优化，同时，给出每条指令在内存中的地址。(1, PC and register groups are clocked. 2, the command memory and data memory storage unit width will use 8 bits, that is, a byte storage unit. 3, the controller part can be considered with the control signal truth table method (common part) and with the case statement method to produce each command other control signal match, Note: the signal must be with the state. The Of course, you can also use other methods to consider their own. 4, try the assembler, and must contain all the required instructions. Slt, sltu instruction must check two cases: "less than" and "greater than or equal to"; beq, bne instruction must check two cases: "wait" and "unequal". This assembler must be optimized as much as possible, giving the address of each instruction in memory.)

此代码可以实现16位二进制和BCD码之间的转换。(This code can realize the conversion between 16 bit binary and BCD code.)

此代码显示的颜色，它需要与 GPIO 连接。希望你喜欢它。它不是我的工作。

数字频率计，测量范围0-1GHZ,测周测频自动转换，精度极高，花了很长时间，不过还是有一点点小问题，有待改进.(Digital frequency meter, range 0-1GHZ, automatic conversion measured weekly frequency measurement, high precision, took a long time, but still a little small problems to be improved.)
