International Classification:

G06F 1/12
G06F 15/16

US Classification:

713400, 345502

Abstract:

A method for testing synchronization between a first graphics processing unit coupled to a second graphics processing unit. The method includes detecting whether an incoming synchronization signal has been received, determining whether the incoming synchronization signal is received from one of the first graphics processing unit, the second graphics processing unit and an external synchronization signal, and indicating on a control panel one of a first and second synchronization input/output ports on one of the first graphics processing unit and the second graphics processing unit as an input port and the other one of the first and second synchronization input/output ports as an output port, if the incoming synchronization signal is received from the one of the first graphics processing unit and the second graphics processing unit.

US Classification:

345502, 345503, 345504, 345505

Abstract:

A method for synchronizing two of more graphics processing units. The method includes the steps of determining whether the phase of a first timing signal of a first graphics processing unit and the phase of a second timing signal of a second graphics processing unit are synchronized, and adjusting the frequency of the first timing signal to the frequency of the second timing signal if the first timing signal and the second timing signal are not synchronized.

Abstract:

A computer implemented method comprising receiving a list of one or more contact points from a sender and comparing the list of one or more contact points to a satellite server's do-not-contact list. Any contact point on the list of one or more contact points that appears on the satellite server's do-not-contact list is reported to the sender. The satellite server's do-not-contact list is generated from a do-not-contact list distributed by a master server. A registrant registers with the master server to provide a registrant contact point to be on the do-not-contact list to be distributed by the master server. The contact points in the registry may be organized in a hierarchy with preferences at one or more levels.

International Classification:

G06T 1/00

US Classification:

345501

Abstract:

Disclosed are a GPU video data preprocessor, a computer device, an apparatus and a method for facilitating expeditious video transfer to graphics memory for enhancing display and video capture applications, among other things. In one embodiment, a graphics preprocessor is used to preprocess video for transit via a graphics processing unit (“GPU”) directly to graphics memory without invoking a graphics driver. The graphics preprocessor includes an input configured to receive video data. It also includes a native data formatter coupled to the input and configured to format the video data as GPU data to conform with the architecture of the GPU. In at least one embodiment, the graphics preprocessor also includes a command execution unit, which can be configured to transmit an instruction executable by the GPU as a transmitted instruction to perform a graphics pipeline operation on the GPU data.

International Classification:

G06F 13/14

US Classification:

345520, 386231

Abstract:

Disclosed are an apparatus, a computer device, a system, computer readable media and a method for using graphics processing unit (“GPU”)-generated data to characterize, in-situ, the ability of a cable to reliably carry digitized video, among other things. In one embodiment, a computing device includes a processor coupled via a system bus to a graphics engine and a video cable-testing apparatus. This apparatus has an input port configured to couple to the digitized video cable to receive pixel data generated by the graphics engine. It also has a signal integrity evaluator (“SIE”) configured to identify the digitized video cable as the source an amount of data corruption, the amount of data corruption being a function of the pixel data. The signal integrity evaluator includes a classifier to classify the amount of data corruption into classes that each represents various degrees of degradation of the computer-generated video images.
