METHOD FOR HANDLING INTERRUPTS FOR AVOIDING CONTEXT SWITCHOVER IN A NON-PRIVILEGE MODE USING A MICROPROCESSOR IN NON PRIVILEGE MODE

摘要

The invention proposes a system and method for handling interrupts in non privilege mode. According to the present invention, a micro processor system consisting of a pseudo device driver and a pseudo intgerrupt service routine in the privilege mode, on receipt of an interrupt, transfers the control to a non privilege mode handler without context switchover. Further with the present invention nesting of interrupts and maintaining interrupt priority levels are also possible.
