The results of a Speed-Independent Fused Multiply-Add (SIFMA) unit pipeline implementation research are presented. SIFMA is compliant with IEEE 754 Standard. A criterion of the SIFMA pipeline’s maximum performance is formulated. A method of reducing hardware costs of SIFMA multiplier by 1.5-2 times depending on its features is offered. The multiplier utilizes a modified Booth algorithm using self-timed redundant code. A new energy efficient self-timed organization of an input and output FIFO was developed. It provides less complexity versus a previous SIFMA implementation on base of semi-dense register.
