40results about How to "Improve bus utilization" patented technology

The application provides a near-memory DMA data transposition controller, a data transposition method, a medium and a product. The near-memory DMA data transposition controller is arranged on a data transmission path between a far-end memory and a near-end memory of an AI computing chip, and comprises a first DMA control module and a second DMA control module. The transposition operation only occurs after data is read from the near-end memory, thereby reducing independent transposition processing links, reducing transposition power consumption overhead and operation delay, avoiding a decrease in bus bandwidth utilization caused by transposition, and reducing hardware resource overhead. A dynamic splitting strategy concentrates non-aligned access in a first data block, thereby improving overall bandwidth utilization. The transposition operation is separated from a computing unit, the transposition is completed synchronously in a data carrying process, computing resources are released, and an operation period and power consumption overhead are reduced.
