ABSTRACT:
An electronic device (PPU 110) includes a data source (7201) supplying data and successive control signals indicative of valid-data, wherein transitions occur in the data during intervals between the signals indicative of valid-data, and a selector (7205) having a first input connected to the data source (7201), and a second input (7214), and an output. A circuit (7207) is connected to the output of the selector (7205) to receive data from the data source (7201) via the selector (7205). A source of a quieting signal (7220) is connected to the second input (7214), and the selector (7205) is responsive to the control signals (7206) to select the quieting signal (7220) during at least a portion of the interval between the signals indicative of valid data, and to select the data source in response to at least some of the successive control signals indicative of valid-data. Other devices, systems and methods are also described.
