Beschreibung
Zusammenfassung:	PLX FP is a floating-point instruction set architecture (ISA) extension to PLX that is designed for fast and efficient 3D graphics processing. In this paper, we explore the implementation and performance of the fundamental functional unit for PLX FP, the floating-point multiply-accumulate (FMAC) functional unit. We present simulation and synthesis results for several implementations with increasingly powerful sets of instructions, to compare area and delay tradeoffs. We also evaluate the performance tradeoffs with examples taken from the 3D graphics processing pipeline.
