Compiler Support for an AI-oriented SIMD Extension of a Space Processor

In this on going research paper, we present our work on the compiler support for an AI-oriented SIMD Extension, called SPARROW. The SPARROW hardware design has been developed during a recently defended, awardwinning Master Thesis and is targeting Cobham Gaisler's space processors Leon3 and NOEL-V. We present the compiler support we have included in two compiler toolchains, gcc and llvm as well as a SIMD intrinsics library for easy programmability. Compiler modifications are kept to minimum in order to enable incremental qualification of the toolchains. We present our experience working with the two compilers and performance results for the two compilers on top an FPGA implementation of the target space processor.
