Methods and apparatus to facilitate read-modify-write support in a victim cache

A system, comprising:

• a processing unit configured to generate a memory operation;
• a cache controller configured to receive the memory operation;
• a first cache storage coupled to the cache controller;
• a second cache storage coupled to the cache controller in parallel with the first cache storage;
• and
• a storage queue coupled to the second cache storage and the cache controller,
• wherein the cache controller is configured to cause, based on the memory operation, the storage queue to:
• receive a first set of data from the first cache storage;
• receive a second set of data from the second cache storage;
• merge the first set of data and the second set of data to produce a third set of data;
• and
• write the third set of data to the second cache storage.

A method, comprising:

• retrieving, by a cache controller, a first set of data from a first cache storage;
• providing the first set of data to a storage queue coupled to a second cache storage;
• retrieving a second set of data from the second cache storage;
• merging, by the storage queue, the first set of data and the second set of data to produce a third set of data;
• and
• storing, by the storage queue, the third set of data in the second cache storage.
