SQRT

hi
i have a block with two 8 bit inputs(I , Q) and SQRT(I*I+Q*Q) in out put which i used cordic algorithm to implement SQRT.but i think there should be better algorithm to get SQRT.
any comment?
tnx in advance
 

SQRT

Most of these algorithms are recursive. You can try Newton-Raphson root finding algorithm. It is the simplest one. Use Google to find details.
