PIM is a computing paradigm where data processing occurs directly within the memory chips (like DRAM) rather than moving it back and forth to a central CPU or GPU. This eliminates the "memory wall"—the performance bottleneck caused by the slow and energy-intensive transfer of data between memory and processors. 2. The CENT Architecture
: Units located near the memory chips that handle intensive computations, such as transformer block operations. 3. Key Advantages of this System pim073.jpg
: CXL-based memory expansion offers approximately 8x lower latency compared to network-based RDMA (Remote Direct Memory Access). PIM is a computing paradigm where data processing
: The CPU sends standard read/write transactions and specialized CENT arithmetic instructions to the device. The CENT Architecture : Units located near the
: By mapping entire transformer blocks to memory channels, the system can facilitate "Pipeline Parallel" processing, allowing LLM execution without relying on high-end GPUs. 4. Technical Workflow
