Load balanced interrupt handling in an embedded symmetric multiprocessor system

摘要

In an embedded symmetric multiprocessor (ESMP) system it is desirable to maintain equal central processing unit load balance. When an interrupt occurs, a single central processing receives the interrupt and then passes information to the central processing unit scheduling software. This software will in turn determine which central processing unit can best handle the interrupt. Because the scheduling software is able to determine which central processing unit handles the interrupt process, it can maintain central processing unit load balancing resulting in better system performance.
