Adaptive line width cache systems and methods

Abstract:

The present disclosure provides techniques for implementing a computing system that includes a processing sub-system, a memory sub-system, and one or more memory controllers. The processing sub-system includes processing circuitry that performs an operation based on a target data block and a processor-side cache coupled between the processing circuitry and a system bus. The memory sub-system includes a memory that stores data blocks in a memory array and a memory-side caches coupled between the memory channel and the system bus. The one or more memory controllers control caching in the processor-side cache based at least in part on temporal relationship between previous data block targeting by the processing circuitry and control caching in memory-side cache based at least in part on spatial relationship between data block storage locations in the memory channel.
