Abstract
A method for operand width reduction is described, wherein two N-bit input operands (A, B) of a bit width of N are processed and two M-bit output operands (A', B′) of a reduced bit width of M are generated in a way, that a post-processing comprising an M-bit adder function followed by saturation to M bits performed on said two M-bit output operands (A′, B′) provides an M-bit result equal to an M-bit result of an N-bit modulo adder function of the two N-bit input operands (A, B), followed by a saturation to M bits. Further an electronic computing circuit () is described performing said method. Additionally a computer system comprising such an electronic computing circuit is described.
