Abstract:
Systems and methods for granular cache repair. An example processing system comprises a processing core communicatively coupled to a cache via a cache controller and a cache repair memory communicatively coupled to the cache controller. The cache controller is configured, responsive to receiving a read request referencing a physical address, to: retrieve cache data from a cache location identified by the physical address, retrieve, in parallel with retrieving the cache data, cache repair data from the cache repair memory, the cache repair data associated with the cache location, the cache repair data comprising at least one of: a bit repair value, a column repair value, and a raw repair value, and output the cache data multiplexed with the cache repair data.
