Customizable instruction cache hierarchy for embedded systems
Date of Issue2005
School of Computer Engineering
Cache hierarchy bridges the ever increasing performance gap between the fast processing core and slow main memory. In an effort to improve the total system performance, the high performance microprocessor designers commit more and more transistor budget for cache memory systems. As a result, power consumption of cache memory subsystems has been increasing notably over each processor generation. Although a number of cache optimization techniques to reduce power consumption have been reported in the literature, power consumption in cache memories is a major concern and accounts for as much as 50% of the total processor power. Since the instruction cache consumes the majority of this power, predictor based schemes have been proposed for the instruction cache hierarchy in an attempt to provide for an overall reduction in the energy delay product.
