Abstract: A multi-core processing system includes a first processing core, a second processing core, a task manager coupled to the first and second processing cores. The task manager is operable to receive context information of a task from the first processing core and provide the context information to the second processing core. The second processing core continues executing the task using the context information.

Abstract: The present invention relates to apparatus and methods for low latency data delivery within multi-core processing systems. The apparatus and method comprises assigning a task to a processing core; identifying a job within the task to be performed via an accelerator; performing and completing the job via the accelerator; generating output data including associated status information via the accelerator, the status information including an associated inactive write strobe; snooping the status information to determine when the job being performed by the accelerator is completed, the snooping comprising snooping the status information; and continuing executing the task using the output data associated with the status information.
