Stencil computation is one of the important kernels in scientific computations, however, the sustained performance is limited by memory bandwidth especially on multi-core microprocessors and GPGPUs due to its small operationalintensity. In this paper, we propose a scalable streaming-array (SSA) of simple soft-processors for high-performance stencil computation on multiple FPGAs. The SSA architecture...
For numerical computations requiring a relatively high ratio of data access to operation, the scalability of memory bandwidth is key to performance improvement. In this paper, we propose a scalable FPGA-array to achieve custom computing machines for high-performance and power-efficient scientific simulations based on difference schemes. With the FPGA-array, we construct a systolic computational-memory...
