摘要： Techniques for selecting a boot display device in the multi-GPU configured computing device include a graphic initialization routine for determining a topology of a plurality of GPUs. It is then determined if a display is coupled to any of the plurality of GPUs. The determination of whether the display is coupled to a GPU is communicated to the other of the plurality of GPUs based upon the determined topology. Thereafter, selection of a given GPU as a primary boot device, by a system initialization routine, is influenced by representing each GPU not coupled to the display as a graphics device and the GPUs coupled to a given display as the primary boot device if one or more displays are coupled to GPUs, and by representing the given GPU as the primary boot device and all other GPUs as graphics devices when the display is not coupled to any of the GPUs. In addition or in the alternative selection of the given GPU as the primary boot device may be influenced by hiding the expansion ROM of GPUs not coupled to a display.

摘要： A jitter analysis system includes an electronic circuit having a noisy electrical signal with jitter along a baseline of the signal. The jitter analysis system also includes a sampling unit coupled to the noisy electrical signal that provides waveform samples of the noisy electrical timing signal and a jitter detection unit coupled to the sampling unit that provides baseline crossings of the noisy electrical signal, wherein the baseline crossings are determined from a selection of the waveform samples proximate the baseline of the signal. A jitter determination method is also provided.
