    incorporates Processing-In-Memory (PIM) chips as smart-memory coprocessors to a microprocessor. This architecture exploits inherent memory bandwidth both on chip and across the system to target several classes of bandwidth-limited applications. A recently developed PIM chip in TSMC 0.18µm technology incorporates a DDR SDRAM interface for its inclusion in commodity systems, such as the HP zx6000 workstation used on this project. Each PIM chip includes eight single-precision floating-point units (FPU) in the WideWord pipeline, enabling significant speedups in the target system. This paper focuses on the integration of new subcomponents into the PIM chip design, system integration, and measured system results, demonstrating the significant GFLOP/W feature offered by PIM computing
