Filed:

Apr 19, 2002

Appl. No.:

10/126739

Inventors:

Jeffrey L. Gilbert - Lake Forest CA, US

Assignee:

Newfrey LLC - Newark DE

International Classification:

E03B001/00

US Classification:

251368, 13762541, 13762531

Abstract:

A valve assembly comprising a valve stem, an annular bonnet configured to receive the valve stem, a valve disk coupled to one end of the valve stem, a seal, and an insert. The seal is disposed adjacent the valve disk and has a top surface and a bottom surface. The top surface includes a first pair of sealing ridges extending upwardly therefrom and the bottom surface includes a second pair of sealing ridges extending downwardly therefrom. The insert includes a recess configured to receive the seal that performs a sealing function and a biasing function. The valve assembly can easily be configured to open in either a clockwise or counterclockwise direction without resort to adapters or other additional pieces by rotating the bonnet/valve stem sub-assembly 90 relative to the insert.

Appl. No.:

10/980737

Inventors:

Jeffrey D. Gilbert - Portland OR, US
Harris D. Joyce - Portland OR, US

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 13/00

US Classification:

710309, 710113

Abstract:

A method and apparatus for improved performance for handling priority agent bus requests when symmetric agent bus parking is enabled is disclosed. In one embodiment, a modified priority agent may be used. The modified priority agent may assert an unused symmetric agent bus request when it asserts its priority agent bus request. When a symmetric agent parks on the bus, continually asserting its symmetric agent bus request, the assertion of the otherwise unused symmetric agent bus request may cause the symmetric agent to withdraw its symmetric agent bus request. This may reduce bus response time for subsequent modified priority agent bus requests.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 12/00

US Classification:

711137, 711167, 711213

Abstract:

A method and apparatus for adaptive multiple line prefetching. In one embodiment, the method includes the identification of a prefetch depth. As described herein, a prefetch depth may refer to a number of memory lines to be prefetched to temporary (cache) memory. Once the prefetch depth is identified, prefetching is performed according to the identified prefetch depth. During the prefetching, the prefetching is adjusted as changes in the prefetch depth are detected. Accordingly, the dynamic adaptive multi-line prefetching mechanism described herein promotes higher system performance by the use of a more efficient prefetching mechanism.

International Classification:

US Classification:

Abstract:

A method and apparatus for cache coherency states is disclosed. In one embodiment, a cache accessible across two interfaces, an inner interface and an outer interface, may have a joint cache coherency state. The joint cache coherency state may have a first state for the inner interface and a second state for the outer interface, where the second state has higher privilege than the first state. In one embodiment this may promote speculative invalidation. In other embodiments this may reduce snoop transactions on the inner interface.

Abstract:

Methods and apparatus to perform direct cache access in multiple core processors are described. In an embodiment, data corresponding to a direct cache access request is stored in a storage unit and a corresponding read request is generated. Other embodiments are also described.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 13/00

US Classification:

711146, 711141

Abstract:

A snoop filter maintains data coherency information for multiple caches in a multi-processor system. The Exclusive Ownership Snoop Filter only stores entries that are exclusively owned by a processor. A coherency engine updates the entries in the snoop filter such that an entry is removed from the snoop filter if the entry exits the exclusive state. To ensure data coherency, the coherency engine implements a sequencing rule that decouples a read request from a write request.
