Abstract
Emerging hardware is shaping the future of heterogeneous computing; however, the use of such extraordinary computing power is restricted to a few software developers with hardware expertise. My research designs software developer tools to democratize heterogeneous computing.
In this talk, I will introduce my recent work on automated program repair and automated test input generation for heterogeneous application development with FPGA. HeteroGen (ASPLOS'22) automatically translates C/C++ code to its high-level synthesis (HLS) version for FPGA acceleration. Key to the success of HeteroGen is adapting the idea of search-based program repair to the heterogeneous computing domain, while addressing two technical challenges. First, the turn-around time of HLS compilation and simulation is much longer than the usual C/C++ compilation and execution time. Second, behavior preservation requires testing, but test cases are often unavailable. I will then describe my work on HeteroFuzz (FSE'21), a fuzzing-based test generation tool, designed to specifically target heterogeneous applications and to detect platform-dependent divergence between CPU and FPGA. This line of research, to our knowledge, is the first attempt to expand the reach of software engineering techniques to the hardware design domain.
