단정도/배정도 승산을 위한 $200-MHz{\circled}a2.5-V$ 이중 모드 승산기
A $200-MHz{\circled}a2.5-V$ Dual-Mode Multiplier for Single/Double-Precision Multiplications
초록
A dual-mode multiplier (DMM) that performs single- and double-precision multiplications has been designed. An algorithm for efficiently implementing double-precision multiplication with a single-precision multiplier was proposed, which is based on partitioning double-precision multiplication into four single-precision sub-multiplications and computing them with sequential accumulations. When compared with conventional double-precision multipliers, our approach reduces the hardware complexity by about one third resulting in small silicon area and low-power dissipation at the expense of increased latency and throughput cycles.
