Multi-mode memory access techniques for performing graphics processing unit-based memory transfer operations

摘要

This disclosure describes techniques for performing memory transfer operations with a graphics processing unit (GPU) based on a selectable memory transfer mode, and techniques for selecting a memory transfer mode for performing all or part of a memory transfer operation with a GPU. In some examples, the techniques of this disclosure may include selecting a memory transfer mode for performing at least part of a memory transfer operation, and performing, with a GPU, the memory transfer operation based on the selected memory transfer mode. The memory transfer mode may be selected from a set of at least two different memory transfer modes that includes an interleave memory transfer mode and a sequential memory transfer mode. The techniques of this disclosure may be used to improve the performance of GPU-assisted memory transfer operations.

主权项

1. A method comprising:
selecting, with one or more processors, a memory transfer mode for performing at least part of a memory transfer operation, the memory transfer mode being selected from a set of at least two different memory transfer modes that includes an interleave memory transfer mode and a sequential memory transfer mode, wherein the sequential memory transfer mode includes alternate issuing of groups of multiple, consecutive read requests and groups of multiple, consecutive write requests during separate time intervals; and performing, with a graphics processing unit (GPU), the memory transfer operation based on the selected memory transfer mode.
