Abstract

A computing system is described that includes a main system bus that remains active while said computing system operates within a non main CPU/OS based operational state. The computing system also includes a controller that operates functional tasks while the computing system is within the non main CPU/OS based operational state. The computing system also includes an I/O unit coupled to the main system bus that remains active while the computing system operates within the non main CPU/OS based operational state.

Claims

1. A computing system, comprising:

a) a main system bus that remains active while said computing system operates within a non main CPU/OS based operational state;

b) a controller that operates functional tasks while said computing system is within said non main CPU/OS based operational state, said controller coupled to said main system bus; and

,

c) an I/O unit coupled to said main system bus that remains active while said computing system operates within said non main CPU/OS based operational state.
