**help needed to . . .**

hi all

i would like to implement following formula on xilinx FPGA

A=(Sqrt(x^2+y^2)*Sqrt(z^2+t^2))/(Sqrt(k^2+H^2)*Sqrt(L^2+M^2))

B=[ArcTan(x/y)-ArcTan(z/t)]-[ArcTan(k/h)-ArcTan(l/m)]

i know i can implement Sqrt and Arctan or even sin , ... by implementing cordic block,but i feel there is better way to do it.

how i can implement exactly with better method?

how about xilinx coregenerator - cordic block , anyone try it?

any comment or idea or help is highly appreciated
