Abstract: A Processing-in-Memory (PIM) computing system and a memory controller provide improved memory traffic efficiency and improved PIM operation efficiency by increasing a burst length of a PIM operation relative to a general memory request. In embodiments, the increased burst length allows the PIM operation to be performed in units of pages, wherein a page is management unit of a memory used in the PIM operation.

Abstract: A Processing-In-Memory (PIM) computing system and a PIM computation offloading method thereof perform PIM computation offloading using a DMA engine. The DMA engine is configured to process a transaction by respectively performing descriptor requests and PIM requests for one or more descriptors stored in a memory, in response to a memory request of a CPU. The memory includes a PIM unit and a memory array, which memory array may be a DRAM. In response to the PIM requests, the PIM unit performs PIM operations using information included in data provided to the DMA engine in response to the descriptor requests.
