Description:
markdown
Accelerator communication is a hot topic today, and things get especially “interesting” when connecting various accelerators into highly heterogeneous SoCs. A major problem comes from mismatches between non-standard custom accelerator interfaces, differing coherency, addressing and memory alignment requirements that software developers have to fix. Hence, these hinder scaling of core to accelerator and inter-accelerator communication. To solve this problem, we built the Cohort platform that lets developers orchestrate their accelerators in a software oriented manner. In particular, we provide a user-friendly and scalable software API based on high-performance shared memory queues and a hardware wrapper around each accelerator. Our prototype, built on top of OpenPiton, improves over the performance of MMIO and coherent DMA and is accessible open source! So, please attend our talk and explore what fun things you can do with your next super heterogeneous SoC!
