Abstract
A method for migration of operations between CPU cores, the method includes: processing, by a source core, one or more tasks and one or more interrupt service routines; accessing a mapping corresponding to a task of the one or more tasks and an interrupt service routine of the one or more interrupt service routines; identifying, based on the mapping, a target core that corresponds to the task and the interrupt service routine; blocking the task from being processed by the source core in response to identifying the target core; in response to identifying the target core, disabling an interrupt corresponding to the interrupt service routine; in response to identifying the target core, assigning the task and the interrupt to the target core; after assigning the interrupt to the target core, enabling the interrupt; and after assigning the task to the target core, processing the task by the target core.
