Ipuloc-Exploring Dynamic Program Locality with the Instruction Processing Unit for Filling Memory Gap

摘要

Memory gap has become an essential factor influencing the peak performance of high-speed CPU-based systems. to fill this gap, enlarging cache capacity has been a tradi- tional method based on static program locality principle. However, the order of instructions stored in I-Cache before being sent to Data Processing Unit (DPU) is a kind of useful infor- mation that has not ever been utilized before. So an architecture containing an Instruction Processing Unit (IPU) in parallel with the ordinary DPU is proposed.
