Error bound reduction for fixed-width modified Booth multiplier

The maximum error has serious effect on the performance of fixed-width multipliers that receive W-bit inputs and produce W-bit products. In this paper, we analyze the error bound of fixed-width modified Booth multiplier. Then, we present a method that can be used to reduce the maximum error. By simulations, it is shown that the performance of the proposed fixed-width multiplier is pretty close to that of the multiplier with rounding scheme.
