verilog source code for cordic for computation of sine and cosine algorithmcordic verilog implementation
OpenCores是一个开源项目,提供了许多硬件描述语言(HDL)的实现,包括Verilog。在这个项目中,Cordic算法被用来实现,并且有流水线和迭代两种方法。 流水线方法是指将计算过程分解成多个步骤,每个步骤都在前一个步骤的基础上进行计算。这种方法可以有效地减少计算时间,提高计算效率。 迭代方法是指通过重复执行相同的计算步骤来...
By using only additions and shift operations CORDIC algorithm calculates the rotation of a vector and it is an iterative algorithm. The design architecture is written in verilog HDL code using Modelsim and XILINX ISE 14.2 tools.Ketana Sudheer Babu...
In software implementations CORDIC enables most of the code and data be shared between routines for trigonometric and hyperbolic functions, helping to conserve memory. CORDIC algorithm is often used to implement rotations needed in modulators and demodulators. CORDIC algorithm was introduced in 1959 by...

CORDIC算法是一种对目标值进行逼近的迭代算法,且迭代次数越多精度越高。迭代过程中仅仅需要除2运算和加减运算,因此特别适合硬件方式实现。在单位圆中,圆上角β点的x坐标和y坐标分别对应β的cos和sin值,因此,求角β的正弦值的CORDICn次迭代过程如下: 1、以(1,0)为初始点,向靠近β的方向旋转arctan(1)=45°得...
