摘要

A coarse-grain reconfigurable architecture is an important technology for exploiting the parallelism of a program without compromise of the flexibility and has been adopted for high-performance embedded systems. However, the utilization of hardware resources may be limited by a large number of conditional executed operations. This paper represents a predicate-aware modulo scheduling which may map disjoint operations into the same processing element to reduce the requirements of hardware resources. Moreover, a weighted mapping decision algorithm has also been proposed to improve the execution performance for reconfigurable architecture. Our experimental results indicate that the initiation interval of a loop of the selected benchmarks may be reduced by 12% to 25.2% compared with a related work.
