Abstract
A processor includes multiple register sets. A different register set may be dedicated to each of one or more interrupt sources, and yet another register set may be dedicated to other (non-interrupt) tasks. The interrupt sources may record interrupt service requests instead of signalling an interrupt to the processor. Periodically, the processor may poll the interrupt sources to determine if a service request is recorded.
