基于动态数据流的粗粒度可重构阵列设计

Design of Coarse-Grained Reconfigurable Array Based on Dynamic Data Flow

为提高粗粒度可重构阵列中运算资源的利用率,基于动态数据流的执行方式设计一个粗粒度可重构阵列,通过令数据携带标记的方式允许不同循环迭代的数据在阵列上乱序执行,充分地利用阵列上的计算资源。基于C++平台设计一个阵列仿真器以模拟阵列的执行过程,仿真结果表明动态数据流驱动的方式能够有效地提升性能,并且随着标记的增多,整体的性能提升越显著。

In order to improve the utilization of computing resources in the coarse-grained reconfigurable array,a coarse-grained reconfigurable array is designed based on the execution mode of dynamic data flow.By making data carry tags,the data of different cycles and iterations can be executed in random order on the array,and the computing resources on the array can be fully utilized.An array simulator is designed based on C++platform to simulate the execution process of arrays.The simulation results show that the dynamic data flow driven approach can ef fectively improve the performance,and the overall performance improvement becomes more significant with the increase of tags.
