Filed:

Mar 18, 2000

Appl. No.:

09/531280

Inventors:

David V. James - Palo Alto CA
Bruce Fairman - Woodside CA
David Hunter - Santa Barbara CA

Assignee:

Sony Corporation - Tokyo
Sony Electronics, Inc. - Park Ridge NJ

International Classification:

G06F 1300

US Classification:

710104, 370258

Abstract:

A method and system for ordering an interconnect topology to form a ring structure, the topology comprising a number of nodes, are described. In one embodiment, a self identifier for each of the nodes is determined. Further, the self identifier is mapped to a ring identifier for each node. In addition, each node computes the ring identifier of one of its port-connected nodes as its topologically adjacent neighbor identifier.

Abstract:

Computer method and apparatus allows instrumentation of program modules while maintaining exception-handling unwinding context. In the case of instrumenting procedure prologues, the invention preserves the calling context. A sanitized copy of the prologue and rewind instructions to reverse the effects of duplicate prologue instructions are employed.

US Classification:

710306, 710307, 710312, 710313, 710310, 710 60, 710 61

Abstract:

A method and system for adjusting the bandwidth allocated for isochronous data traffic on an interconnected data bus is disclosed. The present system uses an isochronous resource manager (IRM) to sense a bandwidth change request from a talker. The IRM instigates a bandwidth adjustment associated with the bandwidth change request to one or more bus bridge portals.

Abstract:

A method and system for using a new bus identifier in an interconnect, and the interconnect including a plurality of nodes and at least one bus bridge. A configuration change is determined on the first bus connected to the plurality of nodes. Each node has a corresponding bus identifier. A new bus identifier is assigned for each node having a changed state if a configuration change is determined on the first bus.

International Classification:

H04L 516

US Classification:

375222, 370464

Abstract:

A transceiver and method for communicating over a communications channel having a plurality of subchannels are described. In particular, the transceiver is capable of dynamically switching between communicating data for a first active application set and communicating data for a second different active application set. An active application set is defined as the set of one or more active applications for which the transceiver is currently communicating data. As part of communicating data for the first active application set, the transceiver allocates the subchannels to the one or more applications in the first application set. The transmission requirements of the first active application set defines a first communication state of the transceiver. When the transceiver dynamically transitions to communicating data for the second different application set, the transceiver reallocates the subchannels to the one or more applications in the second different application set. The transmission requirements of the second different active application set defines a second communication state of the transceiver.
