Abstract

Although run-time reconfigurable systems have been shown to achieve very high performance, the speedups over traditional microprocessor systems are limited by the cost of configuration of the hardware. In this paper, we explore the idea of configuration caching. We present techniques to carefully manage the configurations present on the reconfigurable hardware throughout program execution. Using the presented strategies, we show that the number of required reconfigurations is reduced, lowering the configuration overhead. We extend these techniques to a number of different FPGA programming models, and develop both lower bound and realistic caching algorithms for these structures.
