GPUs are becoming an increasingly attractive option for obtaining performance speedups for data-parallel applications. FPGA technology mapping is an algorithm that is heavily data parallel; however, it has many features that make it unattractive to implement on a GPU. The algorithm uses data in irregular ways since it is a graph-based algorithm. In addition, it makes heavy use of constructs like recursion which is not supported by GPU hardware. In this paper, we take a state-of-the-art FPGA technology mapping algorithm within Berkeley’s ABC package and attempt to parallelize it on a GPU. We show that runtime gains of 3.1x are achievable while maintaining identical quality as demonstrated by running these netlists through Altera’s Quartus II place-and-route tool.
