[ablam]

Altera and Xilinx both provide floating point cores for you to use.

can u just provide me the exact link for the same.it wil be a great help .Thanks in advance

Thanks for the link.I meant for the VHDL code for Floating point multiplication,division,addition.I wanted those codes to use it in my academic works.I wanted it very urgently.it wil be a great help if u provide it

I suggest you check opencores.org.

I take it you are new to opencores as well. ;-) Just take a random sampling of opencores projects, and you'll see what I mean.

I have made this VHDL implementation of floating point addition, subtraction, multiplication, division and square root. You can look at it or use it if you wont. Its in the atachment.

Can u please tel me where is the attachment?i am in badly need of floating point addition,multiplication,division,subtraction VHDL code.Thanks in advance.plz reply

Hai ,

Can u tel me how can i implement the following eqn in VHDL?
h(x,y)=1/(2πσ_g^2 ) exp(-((x^2+y^2)/(2σ_g^2 )) )⁡cos(j2π*(ux+vy))
The code must be synthesizable.Give me the best idea for implementation.thanks in advance

you're gonna need a lot of look up tables and some multipliers.
