Abstract(in English) | Our laboratory has developed a reconfigurable processor DS-HIE based on bit-serial operation. The DS-HIE processor achieves high performance by throughput, because bit-serial computation manner has a large latency. To achieve high performance by throughput with the DS-HIE processor, input timing at each operation unit of the DS-HIE is important. If there is a difference to the input to a operation unit, the DS-HIE cannot achieve high performance. So, to achieve high performance by throughput, it is necessary to generate the data-flow graph which mapped on the DS-HIE and adjusted timing to improve the problem. In this paper, we propose a method to generate an optimized dataflow graph by a compiler. The benchmark programs to evaluate the impact of the optimization were DCT and FIR. The result shows that it can achieve three times higher performance with the optimization. |
