Approximate Radix-8 Booth Multipliers for Low-Power and High-Performance Operation.

The Booth multiplier has been widely used for high performance signed multiplication by encoding and thereby reducing the number of partial products. A multiplier using the radix-$4$ (or modified Booth) algorithm is very efficient due to the ease of partial product generation, whereas the radix- $8$ Booth multiplier is slow due to the complexity of generating the odd multiples of the multiplican...
