Application aware SoC memory cache partitioning

An apparatus comprising:

• a memory storing program instructions;
• and
• a processor coupled to the memory, wherein the program instructions are executable by the processor to:
• calculate a first set of quotas for a plurality of quota groups, wherein:
• one or more data flows map to one or more quota groups of the plurality of quota groups, wherein a quota represents an amount of space in the memory cache;
• cause a memory cache controller to enforce memory cache usage of the one or more data flows according to a corresponding quota, from the first set of quotas, allocated for the plurality of quota groups;
• receive updates regarding the memory cache usage and status of one or more data flows during run-time;
• based at least in part on a determination that a change has occurred in at least one of the memory cache usage or status of the one or more data flows, calculate a second set of quotas for the plurality of quota groups based on an estimated change in bandwidth that would result from a change in a quota, wherein the second set of quotas changes at least one quota of the first set of quotas from a first non-zero amount to a second non-zero amount;
• and
• cause the memory cache controller to enforce the memory cache usage of the one or more data flows according to a corresponding quota, from the second set of quotas, allocated for the plurality of quota groups.

A method comprising:

• calculating a first set of quotas for a plurality of quota groups, wherein:
• one or more data flows map to one or more quota groups of the plurality of quota groups, wherein a quota represents an amount of space in the memory cache;
• causing a memory cache controller to enforce memory cache usage of the one or more data flows according to a corresponding quota, from the first set of quotas, allocated for the plurality of quota groups;
• monitoring the memory cache usage and status of one or more data flows during run-time;
• in response to determining that a change has occurred in at least one of the memory cache usage or status of the one or more data flows, calculating a second set of quotas for the plurality of quota groups based on an estimated change in bandwidth that would result from a change in a quota, wherein the second set of quotas changes at least one quota of the first set of quotas from a first non-zero amount to a second non-zero amount;
• and
• causing a memory cache controller to enforce the memory cache usage of the one or more data flows according to a corresponding quota, from the second set of quotas, allocated for the plurality of quota groups.
