Abstract: A motion desktop, including a moving image, may be presented on a display screen of a processing device. Foreground items such as, for example, icons and associated text, or other information, may appear on a surface of the motion desktop. In embodiments consistent with the subject matter of this disclosure, foreground content may be rendered to a composing surface, which may be an alpha-enabled surface capable of presenting translucent items. A motion desktop module may render content for at least a portion of a background of the motion desktop to a respective shared memory, shared with a composer. The composer may periodically copy the rendered content from the shared memory to the composing surface, where the composer may compose and blend a scene from background and foreground content. The composed scene may then be presented as the motion desktop.

Abstract: A programable gain amplifier (PGA) has an amplifier and a variable resistor that is connected to the output of the amplifier. The variable resistor includes a resistor that is connected to a reference voltage and multiple parallel taps that tap off the resistor. A two-stage switch network having fine stage switches and coarse stage switches connects the resistor taps to an output node of the PGA. The taps and corresponding fine stage switches are arranged into two or more groups, where each group has n-number of fine stage switches and corresponding taps. One terminal of each fine stage switch is connected to the corresponding resistor tap, and the other terminal is connected to an output terminal for the corresponding group. The coarse stage switches select from among the groups of fine stage switches, and connect to the output of the PGA. During operation, one selected tap is connected to the output of the PGA by closing the appropriate fine stage switch and coarse stage switch, where the selected tap defines a selected group of the fine stage switches. Additionally, one fine stage switch is closed in each of the non-selected groups of fine stage switches. In one embodiment, the location of the closed switches in the non-selected groups is the mirror image of the location in an adjacent group. This reduces the transient voltages that occur when tap selection changes from one group to another.

Abstract: A low jitter, high phase resolution phase lock loop incorporating a ring oscillator-type VCO is designed and constructed to operate at a characteristic frequency M times higher than a required output clock frequency. Multi-phase output signals are taken from the VCO and selected through a Gray code MUX, prior to being divided down to the output clock frequency by a divide-by-M frequency divider circuit. Operating the VCO at frequencies in excess of the output clock frequency, allows jitter to be averaged across a timing cycle M and further allows a reduction in the number of output phase taps, by a scale factor M, without reducing the phase resolution or granularity of the output signal.
