Capacity on demand using signaling bus control
First Claim
Patent Images
1. A computing system having a controllable capacity, comprising:
- a processor;
a signaling bus coupled to the processor; and
a means for dynamically changing a percentage of dead cycles on the signaling bus;
wherein the controllable capacity of the computing system is controlled by monitoring demand on the computing system and altering the controllable capacity responsive to demand by controlling a characteristic of the signaling bus; and
wherein the characteristic of the signaling bus is bandwidth; and
wherein bandwidth is controlled using the means for dynamically changing the percentage of dead cycles on the signaling bus.

Abstract
An apparatus and method is disclosed for providing capacity on demand using control to alter latency and/or bandwidth on a signaling bus in a computer system. If additional capacity is required, authorization is requested for additional capacity. If authorized, bandwidth of the signaling bus is increased to provide additional capacity in the computing system. Alternatively, upon authorization, latency of data transmissions over the signaling bus is reduced. In another alternative, upon authorization, memory timings are adjusted to speed up memory fetches and stores.
