Abstract
Included are embodiments of a Multiply-Accumulate Unit to process multiple format floating point operands. For short format operands, embodiments of the Multiply Accumulate Unit are configured to process data with twice the throughput as long and mixed format data. At least one embodiment can include a short exponent calculation component configured to receive short format data, a long exponent calculation component configured to receive long format data, and a mixed exponent calculation component configured to receive short exponent data, the mixed exponent calculation component further configured to received long format data. Embodiments also include a mantissa datapath configured for implementation to accommodate processing of long, mixed, and short floating point operands.
