US 10,372,491 B2 · Execution context migration method and apparatus

Abstract

Methods, apparatuses and storage medium associated with migration between processors by a computing device are disclosed. In various embodiments, a portable electronic device having an internal processor and internal memory may be attached to a dock. The dock may include another processor as well other memory. The attachment of the dock to the portable electronic device may cause an interrupt. In response to this interrupt, a state associated with the internal processor may be copied to the other memory of the dock. Instructions for the computing device may then be executed using the other processor of the dock. Other embodiments may be disclosed or claimed.

Dependent claims

A computing device with migration of execution context, the computing device comprising:

one or more first processors;
first physical memory, coupled with the one or more processors, to store an operating system to be loaded into the physical memory for execution by the one or more processors;
and
an execution management module, to be loaded into the physical memory and operated by the one or more processors, to:
detect an interrupt associated with coupling a hardware component with the computing device, the hardware component having one or more additional processors and additional physical memory coupled with the one or more additional processors;
initialize the one or more additional processors based on the detected interrupt;
and
copy at least part of a state associated with the one or more first processors from the first physical memory to the additional physical memory based on the detected interrupt.
