Method and system of servicing asynchronous interrupts in multiple processors executing a user program

摘要

A method and system of servicing asynchronous interrupts in multiple processors executing a user program. Some of the exemplary embodiments may be a method comprising executing a user program on a first processor and a duplicate copy of the user program on a second processor, receiving an asynchronous interrupt by both the first and second processors, executing an interrupt service routine on the first processor at an agreed system call of the user program executed on the first processor, and executing an interrupt service routine on the second processor at the agreed system call of the user program executed on the second processor.
