I have heard about booth multiplier it is a fast algorithm (by using a two's complemnt addition and right shifts) used for multiplying bianary numbers but what do you mean by radix-4 and radix-8 in it....Please correct me if I am wrong some where....
Hi,
In Radix-4 BM, we take 2-bits of multiplicand in generating one partial product, where as in Radix-8 BM, we take 3-bits of multiplicand for generating one partial product. The number of partial products is less in Radix-8 BM so, it takes less delay in summing them. But Radix-8 Requires Hard multiple which is disadvantage.
