Appl. No.:

11/103319

Inventors:

Paul G. Chan - Oakland CA, US
Ricky C. Hetherington - Pleasanton CA, US

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G06F 13/36

US Classification:

710315, 710306, 710314

Abstract:

A processor including an integrated system interface unit configured to manage multiple I/O interfaces and multiple protocols. A processor includes a plurality of processing cores, a cache comprising a plurality of banks, and a system interface unit coupled to the processing cores and the cache. The system interface unit includes an inbound unit configured to receive inbound transactions from a first I/O unit and a second I/O unit, and an outbound unit configured to convey outbound transactions to either the first I/O unit or the second I/O unit. Each of the first and second I/O units is configured to support different protocols. Prior to conveying transaction data to the system interface, the first I/O unit and second I/O units reformat transaction data to conform to a common format. The system interface receives and stores transaction data in either queues dedicated for cacheable transactions or queues dedicated for non-cacheable transactions. In addition, each of the I/O units may also indicate in the common format whether a given transaction is to be ordered with respect to other transactions.

Inventors:

Paul Sui-Yuen Chan - Vallejo CA, US

International Classification:

G06F 7/00

US Classification:

707803, 707667, 707711, 707741

Abstract:

A system and method to program computers directly from a Web Browser, by cascading sets of retrieval, computation and update requirement specifications to facilitate repetition, decision and execution control logics, without using query, procedural and programming languages. This method provides database product independent Web based access of databases on the Internet with the following capabilities: creating a database dictionary/directory for describing existing or new databases, tables, columns, and data values; creating new databases; searching the directory by keywords to establish entry points to the directory; browsing the directory upward or downward by the user from the entry points to identify information of interest; creating retrieval, computation and update requirement specifications during the directory browsing process; saving, restoring the requirement specifications by name and submitting the requirement specifications to be executed by the computing engine; cascading previously saved requirement specifications as components and sub-components to create newly named requirement specification which can itself be saved or executed.

Assignee:

Raychem Corporation - Menlo Park CA

International Classification:

H01R 424

US Classification:

439412

Abstract:

This invention provides a terminal block or an adaptor where the binding posts and the caps which screw on the binding posts are adapted to receive small wires without breaking or cutting the wires when the cap is installed with normal installation torque for binding posts. The binding posts and cap can also receive large gauge wires and make connection therewith through the insulation on the wire without cutting or braking the conductor in the wire.

International Classification:

H02G 1510

US Classification:

174 93

Abstract:

A telecommunications cable closure for connecting conductors of a multi-core cable via a terminal block to drop wires. The closure has a rotatable window to allow ready access. Drop wires may leave through grommets having slots therein to avoid the need to thread them through holes.

Appl. No.:

7/537205

Inventors:

Gerald L. Shimirak - Danville CA
Paul S. Chan - San Francisco CA

Assignee:

Raychem Corporation - Menlo Park CA

International Classification:

H01R 424

US Classification:

439416

Abstract:

A terminal block, by means of which a multi-core cable is connected to several drop wires, may be repaired by positioning an adapter over its binding posts. The adapter has an aperture into which a non-stripped, non-split, multi-core drop wire can be inserted such that one core of the drop wire is adjacent one binding post. Caps are then screwed onto the binding posts to make contact with respective cores, prebinding posts to make contact with respective cores, preferably by cutting through insulation of the drop wire. The adapter may be adjustable to suit different sizes of terminal block.

G06F 9/38

Abstract:

Methods for read after write forwarding using a virtual address are disclosed. A method includes determining when a virtual address has been remapped from corresponding to a first physical address to a second physical address and determining if all stores occupying a store queue before the remapping have been retired from the store queue. Loads that are younger than the stores that occupied the store queue before the remapping are prevented from being dispatched and executed until the stores that occupied the store queue before the remapping have left the store queue and become globally visible.

Abstract:

A method and system acquires cache line data associated with a load from respective hierarchical cache data storage components. As a part of the method and system, a store queue is accessed for one or more portions of a cache line associated with the load, and, if the one or more portions of the cache line is held in the store queue, the one or more portions of the cache line is stored in a load queue location associated with the load. The load is completed if the one or more portions of the cache line stored in the load queue location includes all portions of the cache line associated with the load.
