Description
Summary:Processing-in-Memory architecture presents a promising solution to alleviate the data movement bottleneck that arises from transferring data between memory and compute units in traditional processor-centric systems, particularly for DNN applications. However, this architecture introduces two inherent overheads: PIM code offloading and data transferring between CPU and memory. To address these issues, we propose two register-based addressing modes, indexed and base-offset addressing, for DMA descriptor-based in-DRAM PIM ISAs. Our full-system performance evaluation demonstrates that the approach significantly reduces the overheads, resulting in up to 1.94x speedup compared to the baseline PIM, additionally only with 4.65 \% area and 8.61 \% power consumption.
