SOFF is an open-source framework that enables OpenCL applications with data-parallel kernels to run on FPGAs. It consists of three components: an OpenCL-C-to-Verilog compiler (soff-compiler), a board support package (soff-hardware-*), and a runtime system (soff-runtime).
SOFF automatically synthesizes a datapath to execute many OpenCL kernel threads in a pipelined manner. It also synthesizes an efficient memory subsystem for the datapath based on the characteristics of OpenCL kernels. Unlike previous high-level synthesis techniques, SOFF adopts a formal way to handle variable-latency instructions, complex control flows, OpenCL barriers, and atomic operations that appear in real-world OpenCL kernels. SOFF is the first OpenCL framework that correctly compiles all applications in the SPEC ACCEL benchmark suite.
