ABSTRACT:
A system and method of recovering from errors in a data processing system. The data processing system includes one or more processor cores coupled to one or more memory controllers. The one or more memory controllers include at least a first memory interface coupled to a first memory and at least a second memory interface coupled to a second memory. In response to determining an error has been detected in the first memory, access to the first memory via the first memory interface is inhibited. Also, the first memory interface is locally restarted without restarting the second memory interface.
