System and method for improved memory performance using cache level hashing

A system for cache-level memory management in a system on a chip (“SoC”), the system comprising:

• for each of one or more clients, means for determining eligibility for hashing transaction traffic;
• for each of the one or more clients that is determined to be eligible for hashing transaction traffic, means for selecting a customized hashing algorithm;
• for each of the one or more clients that is determined to be eligible for hashing transaction traffic, means for applying its customized hashing algorithm to read and write transactions associated with a low level cache;
• and
• for each of the one or more clients determined to be eligible for hashing transaction traffic, means for directing hashed read and write transactions from the low level cache to a memory controller associated with a multi-bank memory device accessible by all of the one or more clients, wherein the hashed read and write transactions are fulfilled from different banks of the multi-bank memory device.

A system for cache-level memory management in a system on a chip (“SoC”), the system comprising:

• one or more cache index hash modules operable to:
• select a customized hashing algorithm;
• apply the customized hashing algorithm to read and write transactions associated with a low level cache;
• and
• direct hashed read and write transactions from the low level cache to a memory controller associated with a multi-bank memory device accessible by a plurality of clients, wherein the hashed read and write transactions are fulfilled from different banks of the multi-bank memory device.

A computer program product comprising a non-transitory computer usable device having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for cache-level memory management in a system on a chip (“SoC”), said method comprising:

• for each of one or more clients, determining eligibility for hashing transaction traffic;
• for each of the one or more clients that is determined to be eligible for hashing transaction traffic, selecting a customized hashing algorithm;
• for each of the one or more clients that is determined to be eligible for hashing transaction traffic, applying its customized hashing algorithm to read and write transactions associated with a low level cache;
• and
• for each of the one or more clients determined to be eligible for hashing transaction traffic, directing hashed read and write transactions from the low level cache to a memory controller associated with a multi-bank memory device accessible by all of the one or more clients, wherein the hashed read and write transactions are fulfilled from different banks of the multi-bank memory device.
