Dual-Tree Error Compensation for High Performance Fixed-Width Multipliers.

In this paper, a new error-compensation network for fixed-width multipliers is proposed. The error-compensation block is composed of two summation trees which are optimally chosen in order to minimize either the mean-square error or the maximum absolute error. The new technique substantially improves error performances with respect to previously proposed approaches. Simulation results show that new fixed-width multipliers exhibit significant improvements both in propagation delay and in power dissipation with respect to previous solutions. [ABSTRACT FROM AUTHOR]
