Dynamically reconfigurable processors such as the Dynamically Reconfigurable Processor (DRP) released by NEC Electronics are composed of many interconnected coarse-grained arithmetic blocks. Applications for DRP are described in a programming language like C and parallelism in the source code is automatically extracted by a compiler. At the same time; it is also important to optimize descriptions so that the potential performance of the device is effectively brought out. In this paper; we propose an optimized coding method to improve efficiency of parallel processing on DRP. In this technique; the same kind of multicycle operations are aggregated into single functions; keeping the sequential framework of a programming language. The effects of the method are evaluated with ray tracing processing as an example application. As a result; the proposed technique achieves 2.68 to 3.09 times performance improvement without large increase in the number of states nor severe degradation of the frequency. © 2007 Wiley Periodicals; Inc;
