CORDIC算法的硬件实现 用的verilog语言-CORDIC algorithm Hardware Implementation of the Verilog language

MIG IP控制DDR3读写测试，于MIG IP核用户接口时序较复杂，这里给出扩展接口模块用于进一步简化接口时序。(MIG IP controls DDR3 reading and writing tests, and the time sequence of MIG IP kernel user interface is more complex.)

用verilog编写的I2C——E2PROM模型。适用于各种型号的E2PROM，代码内部有参数可选。(Written in verilog I2C- E2PROM model. E2PROM, the internal code applicable to various types of optional parameters.)

这通过反馈来实现一个 17 位伪随机的无符号计数器异或的位 0 和 3。 注意 ︰ 如果也绝不是独家使用相反，这会反相平行的位模式 & 这将意味着所有位都零是一种有效模式和所有那些不都是有效。  目前所有的都是有效的。
