Abstract
A method and apparatus for operating a computer system at the interrupt level. Rather than having a primary task list that is interrupted to service interrupts, all tasks derive from interrupts. To this end, interrupt-time data structures and representations are precomputed and represented. The taxonomy of real time data types is organized. It is preferable to include isochronous media, together with supporting algorithms and heuristics.
Claims4
A system of providing computer processing resources, comprising:
- on a computer system with computer processing resources, scheduling processing tasks on an interrupt-only basis,
- pre-assigning a first planned task as a first class of interrupt,
- pre-assigning a second planned task as a second class of interrupt,
- executing a computer program including said first planned task and said second planned task,
- when said first planned task is to be performed, invoking said first class of interrupt and
- when said second planned task is to be performed, invoking said second class of interrupt, whereby essentially every task on said computer is invoked as a class of interrupt.
