Filed:

Sep 9, 2004

Appl. No.:

10/937049

Inventors:

Naveen Gupta - Fremont CA, US
Ghasi R. Agrawal - Sunnyvale CA, US

Assignee:

LSI Logic Corporation - Milpitas CA

International Classification:

G06F 7/60
G06F 17/50

US Classification:

703 2, 703 14, 703 18

Abstract:

A pin-based memory power modeling method using arc-based characterization includes steps as follows. All power arcs of a memory model are identified and characterized. A power arc is selected from the identified and characterized power arcs. Output bus switching power is computed by removing overlapping power using the selected power arc, and a temporary value for various input ramp times and output loads is derived. Output pin power for the selected power arc is calculated using the temporary value and a ratio of a number of output bits switching over an entire bus width. Switching power for the selected power arc is calculated by a power estimation tool based on port activity and an input intrinsic power value.

Appl. No.:

12/350175

Inventors:

Yogesh B. Gianchandani - Ann Arbor MI, US
Naveen Gupta - Ann Arbor MI, US

International Classification:

F04B 37/02

US Classification:

417 51

Abstract:

A system and method for using an element made of porous ceramic materials such as zeolite to constrain the flow of gas molecules to the free molecular or transitional flow regime. A preferred embodiment of the gas pump may include the zeolite element, a heater, a cooler, passive thermal elements, and encapsulation. The zeolite element may be further comprised of multiple types of porous matrix sub-elements, which may be coated with other materials and may be connected in series or in parallel. The gas pump may further include sensors and a control mechanism that is responsive to the output of the sensors. The control mechanism may further provide the ability to turn on and off certain heaters in order to reverse the flow in the gas pump. In one embodiment, the pump may operate by utilizing waste heat from an external system to induce transpiration driven flow across the zeolite. In another embodiment, the pump may selectively drive and direct gas molecules depending on the molecular size and the interaction between the gas molecule and the zeolite element.

US Classification:

Abstract:

In accordance with embodiments of the present invention, there are provided mechanisms and methods for modeling data services. These mechanisms and methods for modeling data services make it possible for organizations to lessen dependence on service implementations. In an example embodiment, modeling provides a unified view of disparate services to one or more requestors. Requestors may be users, proxies or automated entities. The view of data services provided to the requestor may be substantially independent of structure or format of the data services underlying the model. The data services underlying the model are mapped to the view. This ability of a liquid data framework to support modeling data services makes it possible to attain improved usage from computing resources in a computer system. In other example embodiments, multiple models of data services may be created, stored and used to increase flexibility in changing or adapting the organization's IT infrastructure.
