Abstract: A computing method and system is presented that modifies a standard operating system utilizing two or more processing units to execute continuous processing tasks; such as processing or generating continuous audio, video or other types of data. One of the processors is tasked with running the operating system while each processing unit is dedicated towards running a single continuous processing task. Communication is provided between both processors enabling the continuous processing task to utilize the operating system without being affected by any operating system scheduling requirements.

Abstract: A method for running real time tasks alongside a general purpose operating system, such that the real-time tasks are not pre-emptible by the general purpose operating system, and the general purpose operating system runs as if the real-time tasks were not present. This is achieved by disabling all interrupts except one, which is given to the real time tasks, and then periodically polling the hardware devices, notifying the general purpose operating system of hardware events and the passage of time as and when is necessary.
