| Abstract(in English) | DMA transfer between a CPU and an FPGA often becomes a bottleneck of current reconfigurable machines. To mitigate this problem, the DMA transfer of SRC-6 supports streaming processing with a on-board memory interleave. However, as a preprocessing of the interleave, the CPU must reorder the data for applications with severe FPGA resource constraints. This paper empirically evaluates this overhead to reveal the trade-off point. The results show that the speedup is achieved by interleaved streaming DMA when FPGAs treat 150KB or lower of data per stream. |
