US Patent:

Filed:

Apr 20, 2000

Appl. No.:

09/553587

Inventors:

Mark Shaw - Dallas TX

Assignee:

Hewlett Packard Development Company, L.P. - Houston TX

International Classification:

G06F 1130

US Classification:

714 55, 714 48

Abstract:

In the present invention, a coordinated hierarchy of timing mechanisms preferably cooperate to report errors at different operational levels of a complex of computing devices. Preferably, each timer is able to identify a failure condition at its own level of operation and transmit a time-out condition to a higher level device which may also be a timer. Upon generation of a time-out condition, a system component experiencing a fault condition preferably continues to operate in a degraded mode, informs devices attempting to communicate with the faulty component of a status of the fault condition, and preferably proceeds to identify and correct a failure which caused the time out condition. The timers may be implemented in hardware or software.

Appl. No.:

10/336430

Inventors:

Mark E. Shaw - Garland TX, US
Gary B. Gostin - Plano TX, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F012/00

US Classification:

711165

Abstract:

An embodiment of the invention provides a method for migrating data from one location to another comprising establishing a new memory location under control of a specific memory accessing device. The new memory location being where data, which is being migrated from a first memory location, is to be resident, the specific accessing device taking control of a certain portion of data resident at the first memory location, the control preventing the certain data from being accessed by any device other than the specific accessing device, obtaining, under control of the specific accessing device, a most recent version of the certain data from the first memory location, forwarding the obtained certain data to the new memory location, and when the obtained certain data is forwarded to the new memory location, marking the certain data as being gone from the first memory location such that attempts to access the certain data at the first memory location from a specific accessing device will be redirected back to the accessing device for redirection to the new memory location.

US Classification:

710317, 711118

Abstract:

A system and method for facilitating communications between a plurality of devices that communicate using different cache-line sizes are disclosed. Briefly described, in architecture, one exemplary embodiment of a compatible cache-line communication system employs a plurality of first ports, each first port configured to receive communications from a first type of device that uses a first cache-line size; and a plurality of second ports, each second port configured to receive communications from a second type of device that uses a second cache-line size, such that communications between the first type of devices are enabled over a plurality of first routes, such that communications between the second type of devices are enabled over a plurality of second routes, and such that communications between the first type of devices and the second type of devices are disabled.
