timer，不包含接口文档，只有源代码，复位信号根据需求是同步复位还是异步复位自己加
timer, does not contain the interface documentation, only the source code, according to the needs of the reset signal reset is synchronous or asynchronous resets itself plus (2016-05-05, VHDL, 2KB, 下载1次)
CORDIC（Coordinate Rotation Digital Computer）算法即坐标旋转数字计算方法，是J.D.Volder1于1959年首次提出，主要用于三角函数、双曲线、指数、对数的计算。该算法通过基本的加和移位运算代替乘法运算，使得矢量的旋转和定向的计算不再需要三角函数、乘法、开方、反三角、指数等函数。
CORDIC (Coordinate Rotation Digital Computer) algorithm that coordinate rotation digital computation method is JDVolder1 first proposed in 1959, mainly for trigonometric, hyperbolic, exponential, to calculate the number. The algorithm basic addition and shift operations instead of multiplication, such that rotation of the orientation vector calculations and no longer need to trigonometric functions, multiplication, square root, inverse trigonometric, exponential and other functions.

这是本人自己亲手用MLUTISIM做的一个分数维混沌系统的电路，对开始研究分数未混沌系统的学者具有实际意义。
This is my own personally MLUTISIM do with a fractal dimension of chaotic systems circuit, began to study scores of chaotic systems is not a scholar with practical significance. (2009-04-15, VHDL, 1KB, 下载21次)
