Binary Decoding

NVIDIA’s software does not offer translation of as- sembly code to binary for their GPUs, since the specifications are closed-source. This work fills that gap. We develop a systematic method of decoding the Instruction Set Architectures (ISAs) of NVIDIA’s GPUs, and generating assemblers for different generations of GPUs. Our framework enables cross-architecture binary analysis and transformation. Making the ISA accessible in this manner opens up a world of opportunities for developers and researchers, enabling numerous optimizations and explorations that are unachievable at the source-code level. Our infrastructure has already benefited and been adopted in important applications including performance tuning, binary instrumentation, resource allocation, and memory protection.
