Apparatus and method for deferral scheduling of tasks for operating system on multi-core processor

An apparatus for scheduling of tasks for an operating system on a multi-core system, the apparatus comprising:

• a memory;
• a multi-core processor comprising a plurality of cores;
• and
• an operating system (OS) to execute on the multi-core processor,
• wherein the OS comprises a modular scheduler,
• wherein the modular scheduler is coupled to the multi-core processor and the memory and is configured to:
• receive a system call for initiating a scheduling operation on a second core;
• invoke a scheduling instance to the second core, wherein the scheduling instance notifies the scheduling operation based on a priority of the tasks;
• and
• defer a switching context instance at the second core, and
• execute the deferred switching context instance when an interrupt is received by the second core.
