Allocating memory based on performance ranking

摘要

A method for optimizing memory bandwidth using bank-based memory allocation is described. The method includes receiving a request for an allocation of memory. In response to receiving the request, memory is allocated to the request based on a performance ranking of memory banks in a plurality of memory banks. A performance ranking of a particular memory bank may be based at least in part on both a busyness and a row hit ratio of the particular memory bank. Apparatus and computer readable media are also described.

主权项

1. An apparatus, comprising:
at least one processor; and at least one storage including computer program code stored thereon, that, when executed by the at least one processor, causes the apparatus to:
determine a performance metric for at least a portion of a memory bank of a memory, wherein the performance metric is based at least in part on a busyness measure of at least the portion of the memory bank and a row hit ratio measure of at least the portion of the memory bank; andcause data stored on at least the portion of the memory bank to be re-allocated based at least in part on the performance metric.
