ABSTRACT:
Aspects for performing a multiply-accumulate operation on floating point numbers in a single clock cycle are described. These aspects include mantissa logic for combining a mantissa portion of floating point inputs and exponent logic coupled to the mantissa logic. The exponent logic adjusts the combination of an exponent portion of the floating point inputs by a predetermined value to produce a shift amount and allows pipeline stages in the mantissa logic, wherein an unnormalized floating point result is produced from the mantissa logic on each clock cycle.
