Designing the TFP microprocessor
P.Y.-T. Hsu · IEEE Micro · 1994
Designed to efficiently support large, real-world, floating-point-intensive applications, the TFP (short for Tremendous Floating-Point) microprocessor is a superscalar implementation of the Mips Technologies architecture. This floating-point, computation-oriented processor uses a superscalar machine organization that dispatches up to four instructions each clock cycle to two floating-point execution units, two memory load/store units, and two integer execution units. Its split-level cache structure reduces cache misses by directing integer data references to a 16-Kbyte on-chip cache, while channeling floating-point data references off chip to a 4 Mbyte cache.>
