Abstract
A method includes predicting a memory access pattern of each master of a plurality of masters. The plurality of masters can access a multi-channel memory via a crossbar interconnect, where the multi-channel memory has a plurality of banks The method includes identifying a page size associated with each bank of the plurality of banks The method also includes assigning at least one bank of the plurality of banks to each master of the plurality of masters based on the memory access pattern of each master.
Claims43
An apparatus, comprising:
- a crossbar interconnect configured to:
