Abstract : In this work we present some improvements on hardware operators dedicated to the computation of power operations with fixed integer exponent (x^3, x^4, ...) in unsigned radix-2 fixed-point or integer representations. The proposed method reduces the number of partial products using simplifications based on new identities and transformations. These simplifications are performed both at the logical and the arithmetic levels. The proposed method has been implemented in a VHDL generator that produces synthesizable descriptions of optimized operators. The results of our method have been demonstrated on FPGA circuits.
