Abstract
Embodiments for implementing a fused multiply-multiply-accumulate ('FMMA') unit by one or more processors in a computing system. Mantissas for two products, an exponent difference of the two products serving as an alignment shift amount for a product of the two products having a smallest exponent, and an alignment shift amount for an addend relative to an alternative product of the two product having a larger exponent may be determined in parallel. The addend may be aligned relative to the alternative product having the larger exponent. The product having the smallest exponent may be aligned relative to the alternative product having the larger exponent according to the alignment shift amount.
