Re: multiplier
 
hi
i studied about multiplication and trying to write a code for it. The best combination for small multiplication is Booths algorithm as it reduces the partial product and wallace tree increases the speed of addition of multiplication. i am trying to write a code for modified boothsradix4 algorithm using wallace tree (3:2).. if you can help please do help me..

Thanks

What part of this do you need help with? Also, what is the purpose of
writing this code? Are you designing a chip? Most FPGAs incorporate
pretty durn fast multipliers these days, no need to reinvent the wheel.

Are you just doing this to learn about the techniques?
