Abstract
Software-managed architectures, which use scratch-pad memories (SPMs), are a promising alternative to cached-based architectures for multicores. SPMs provide scalability but require explicit management. For example, to use an instruction SPM, explicit management code needs to be inserted around every call site to load functions to the SPM. such management code would check the state of the SPM and perform loading operations if necessary, which can cause considerable overhead at runtime. In this paper, we propose a compiler-based approach to reduce this overhead by identifying management code that can be removed or simplified. Our experiments with various benchmarks show that our approach reduces the execution time by 14% on average. In addition, compared to hardware caching, using our approach on an SPM-based architecture can reduce the execution times of the benchmarks by up to 15%.
