Abstract
Some field programmable gate arrays (FPGAs) can be partially dynamically reconfigurable with heterogeneous resources distributed on the chip. FPGA-based partially dynamically reconfigurable system (FPGA-PDRS) can be used to accelerate computing and improve computing flexibility. However, the traditional design of FPGA-PDRS is based on manual design. Implementing the automation of FPGA-PDRS needs to solve the problems of task modules partitioning, scheduling, and floorplanning on heterogeneous resources. Existing works only partly solve problems for the automation process of FPGA-PDRS or model homogeneous resource for FPGA-PDRS. To better solve the problems in the automation process of FPGA-PDRS and narrow the gap between algorithm and application, in this paper, we propose a complete workflow including three parts: pre-processing to generate the lists of task module candidate shapes according to the resource requirements, exploration process to search the solution of task modules partitioning, scheduling, and floorplanning, and post-optimization to improve the floorplan success rate. Experimental results show that, compared with state-of-the-art work, the pre-processing process can reduce the occupied area of task modules by 6% on average; the proposed complete workflow can improve performance by 9.6%, and reduce communication cost by 14.2% with improving the resources reuse rate of the heterogeneous resources on the chip. Based on the solution generated by the exploration process, the post-optimization process can improve the floorplan success rate by 11%.
