A generalized network flow based algorithm for power-aware FPGA memory mapping

Published: 08 June 2008 Publication History

Abstract

In this paper, we present a generalized network flow based algorithm for power-aware FPGA memory mapping. Our algorithm not only maps user-defined logical memories to physical embedded memory blocks under the memory resource constraint but also achieves minimum power consumption. The experimental results show that our algorithm was always able to efficiently generate optimal solutions for all test cases while an existing greedy method could do so only for about one third of the test cases.
