High-level synthesis from OpenCL has shown significant potential, but current approaches conflict with mainstream OpenCL design methodologies due to 1) orders-of- magnitude longer FPGA compilation times; and 2) limited support for changing or adding kernels after system compilation. In this paper, we introduce a backend synthesis approach for potentially any OpenCL tool, which uses virtual coarse-grained reconfiguration contexts to speedup compilation by 4211x, while also enabling 144x faster reconfiguration to support different kernels and rapid changes to kernels.
