Workload adaptive address mapping

摘要

Embodiments of the invention describe an apparatus, system and method for workload adaptive address mapping. Embodiments of the invention may receive a request to initialize a system memory including a plurality of memory banks. Using a plurality of memory address mapping schemes for memory settings for the system memory, a system characterization workload is executed during the initialization of the system memory, the system characterization workload including a plurality of transactions directed towards the system memory. Embodiments of the invention may monitor target addresses of the plurality of transactions directed towards the system memory. One of the plurality of memory address mapping schemes is selected based, at least in part, on the target addresses of the plurality of transactions.

1. A method comprising:
receiving a request to initialize a system memory including a plurality of memory banks; and during the initialization of the system memory:
executing, using a plurality of memory address mapping schemes for memory settings for the system memory, a system characterization workload including a plurality of transactions directed towards the system memory, by monitoring target addresses of the plurality of transactions directed towards the system memory;determining, for each memory address mapping scheme:
a number of accesses for each memory bank, andwhich bank of the plurality of banks has a highest number of memory accesses;selecting one of the plurality of memory address mapping schemes for memory settings for the system memory based, at least in part, on:the target addresses of the plurality of transactions, anda determination of which memory address mapping scheme results in a lowest number of memory accesses among the banks determined to have the highest number of memory accesses.
