Abstract
A fixed-point multiplier providing reduced energy usage dynamically truncates received operands according to the location of computationally important bits in the operands and provides the truncated operands to a reduced width multiplier offering reduced energy usage. Information about the location of the dynamic truncation is used to properly shift the result of the multiplier to provide an approximation of full multiplication of the operands.
