Abstract
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.
Claims4
A data processing method employing a plurality of central processing units, said method comprising the steps of:
- scheduling tasks among said plurality of central processing units;
- receiving an external interrupt on a predetermined central processing unit;
- and
- scheduling interrupt tasks among said plurality of central processing units.
