Abstract:One of the most critical aspects of integrating loosely-coupled accelerators in heterogeneous SoC architectures is orchestrating their interactions with the memory hierarchy, especially in terms of navigating the various cache-coherence options: from accelerators accessing off-chip memory directly, bypassing the cache hierarchy, to accelerators having their own private cache. By running realsize applications on FPGA-based prototypes of many-accelerator multi-core SoCs, we show that the best cache-coherence mod… Show more
