| Abstract(in English) | We propose array-structured custom-computing machines for high-performance difference scheme computation. The performance of the machines is in proportion to the number of PEs, because of the array structure of PEs. To achieve higher performance, we are implementing a large PE-array with an FPGA-array consisting of a lot of FPGAs. For the FPGA-array, the bandwidth between FPGAs limits the overall performance. In this paper, we show that actual computation requires narrower bandwidth than the full bandwidth due to sparse data-transer requirement. And then, we present a hardware structure to exploit the sparse data-transfer for narrower bandwidth in the inter-FPGA communication. |
