Abstract
Reconfigurable compilers have shown significant promise in the field of reconfigurable computing, and pipeline scheduling algorithms are typically concerned with improving iteration performance or saving the resources. However, the lack of loop pipeline scheduling algorithm for reconfigurable systems hampers the widespread adoption of fine-grained reconfigurable compilers. This paper presents an improved FPGAs-based loop pipeline scheduling algorithm and has realized it in ASCRA (Application-Specific Compiler for Reconfigurable Architecture) compilation framework. In FPGAs-based loop pipeline scheduling algorithm, the adequate consideration of hardware operation logic delay can save the resources of pipelining and ensure the performance of reconfigurable systems. Both of iterations with carried dependencies and without carried dependency have been considered. The preliminary experiment results show that it can economize more than 20% of the register resources by combining the adjacent pipeline stages without influencing the performance, and the algorithm is feasible for the other fine-grained reconfigurable compilers.
