Input/output unit for a processor of a computer system having partitioned functional elements that are selectively disabled
First Claim
1. In a computer system containing at least one processor subsystem, apparatus, for selectively disabling certain elements of said processor subsystems, comprising:
- a processor unit;
an input/output unit, connected to said processor unit, being partitioned into a plurality of functional elements; and
a functional element controller connected to each functional element, for selectively disabling said functional elements.

Abstract
In a computer system containing at least one processor subsystems, an apparatus and a method for selective disabling processor subsystems using functional segmentation of the input/output circuitry. Each processor subsystem has a processor unit that is connected to an input/output unit. The input/output unit is partitioned into functional elements which are connected to other input/output units of other processor subsystems in the plurality of processor subsystems or to data sources and data sinks. The I/O unit further contains a functional element controller for selectively disabling and enabling the functional elements.
