Hi all!
I'm working on 32-bit assembler implementation for sqrt() and atan2()
functions on 16-bit C54X or/and C55X machine.
Can anybody suggest me some open cores or commercial libraries?
Possible I need later another math functions.
Thanks in advance

hi,

from your question (sqrt +atan2), i guess you are looking for
simultaneous modulus and phase computation of a complex value.
search for "CORDIC" in google, because this algorithm can compute both
values simultaneously.
