Abstract:
A method and apparatus for performing memory access operations during a memory relocation in a computing system are disclosed. In response to initiating a relocation operation from a source region of memory to a destination region of memory, copying one or more lines of the source region to the destination region, and activating a mirror operation mode in a communication circuit coupled to one or more devices included in the computing system. In response to receiving an access request from a device, reading previously stored data from the source region, and in response to determining the access request includes a write request, storing new data included in the write request to locations in both the source and destination regions.
