how to implmathmatical function in fpga such as cos,sin etc

[rubnawaz]

i have to implement math functions in fpga.
one way is to express sine function in term of its maclauran series. since in maclauran series we have to compute factorial,divide, add,subtract arithmatics to find sine function which is very lenthy.

CORDIC algorithm is used to find sin/cos values in Hardware design. Often look up tables are also used.

using cordic algorithm is best.... see more on:

Its good to use cordic algorithum, because it is common to all sin, cos, tan etc.
instead of writing separate series to each.
