Intermediate cache management for non-uniform memory architecture

A processing system comprising:

• a cache configured to store local data accessed from a local memory via a local memory channel and non-local data accessed from a non-local memory via a non-local memory channel;
• and
• a cache controller configured to:
• assign a priority to the local data and a priority to the non-local data based on a cache replacement policy;
• select data for replacement at the cache based on the assigned priorities;
• and
• adjust the priority of the local data stored at the cache and the priority of the non-local data stored at the cache based on a proportion of the local data to the non-local data stored at the cache.

A processing system, comprising:

• a cache at a first subset of dies of the processing system;
• and
• a cache controller configured to:
• adaptively prioritize one of local data and non-local data for replacement at the cache based on a cache replacement policy and a proportion of local data to non-local data stored at the cache, wherein:
• local data comprises data accessed from a local memory at the first subset of dies via a local memory channel;
• and
• non-local data comprises data accessed from a non-local memory at a second subset of dies of the processing system via a non-local memory channel.
