Parallel Decoding for Multi-Stage BCH Decoder
3D heterogeneous processor (commonly termed as 3DHP) integrating multiple processor (such as CPU/GPU) and DRAM dies vertically interconnected by a massive number of Through-Silicon Vias (TSVs) is expected to address the limited bandwidth, high latency and energy consumption of off-chip DRAM. However, spatial and temporal variability due to hotspots in on-chip thermal gradient may result in wide bit error rate variation in DRAM dies. A multi-path BCH decoder has been recently proposed to efficiently address this issue. In this paper, a novel parallel decoding approach for the Multi-Stage BCH decoder is proposed and validated. The proposed approach efficiently leverages the multiple decoding paths to decode multiple words and minimizes the overall decoding latency.
