Abstract
A method can include storing first instruction data in a first region of a nonvolatile memory device; mapping addresses of the first region to predetermined memory address spaces of a processor device; executing the first instruction data from the first region with the processor device; receiving second instruction data for the processor device. While the first instruction data remains available to the processor device, the second instruction data can be written into a second region of the nonvolatile memory device. By operation of the processor device, addresses of the second region can be remapped to the predetermined memory address spaces of the processor device; and executing the second instruction data from the second region with the processor device.
