    摘要: 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.

    摘要: 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.
