Cordic sine and cosine
Cordic can also be used to calculate other math functions like sin and cos let's say you have the coordinates (x, y) of a point and you want to calculate the . Hi all experts i want to use the cordic ip for finding the sin and cosine values what is the ip setting to use it i am using vivado 20143. The cordic approach is to replace the cosine portion of this rotation matrix with a 1 , and the sine portion with a 2^-k. The cordic components provide both rotation or vectoring mode based on a when calculating sin and cos, the output is constrained to the range +/-10.
Cordic also known as volder's algorithm, is a simple and efficient algorithm to calculate his research led to an internal technical report proposing the cordic algorithm to solve sine and cosine functions and a prototypical computer. (cordic) algorithm implemented in parallel architecture to this work is to obtain resource and power efficient sin and cos fpga implementa. Here is a pretty fast routine for determining sin and cos at the same time, and atan2 and the hypotenuse at the same time it was modified from.

Cordic algorithm computes the sine and cosine of angle a is the magnitude of the input vector v=(x,y)t, scaled by a cordic specific. Cordic is a c++ library which uses the cordic algorithm to evaluate certain functions, in particular the sine and cosine. The cordic algorithm was introduced in 1959 by jack volder  this algorithm makes it possible to perform rotations (and therefore to compute sine, cosine,.
Functions given an angle θ, -π/2 θ π/2, the cordic equations for approximating the sine and cosine of θ are xk+χ = xk - δkyk2-k yk+χ = yk + δkxk 2 -k.
