Paper Abstract

An extensive study has been made of the reconfigurable Cell-Array processor that realizes very high-speed parallel computations. Our processor is featured by the architecture such that the configuration can be dynamically and optimally rearranged in real-time by changing the pipeline length or the registry-area depth in macro-Cell units of memories and accumulators. In this processor, therefore, a much smaller size of instruction codes and also a much shorter reconfiguration time are required than in the conventional FPGAs with small-scale logic layers. This paper described a newly developed compiler as the alternative to that using the circuit designs, which requires a long labor even with a well-trained skill. This compile application analyzes a program written with the C-language, using the C-Language is able to use a lot of programs of the past, and produces instruction codes containing information about hardware configurations. According to the structure of hardware used, the compiler can find out the optimal configuration, involving the most efficient depth of pipelined accumulations and parallel calculations. The details of the program analysis are shown with the utility of the compiler in the reconfigurable cell-array processor.
