Abstract:
An apparatus for merging pixel data comprising:a buffer operable for receiving first pixel data from a first source; first selection circuitry operable for receiving said first pixel data from said buffer and second pixel data from a second source, wherein said first selection circuitry selects for outputting said first pixel data from said buffer and second pixel data received from said second source, said first selection circuitry being operable for outputting said first pixel and second pixel data to a display device, and wherein said buffer outputs said first pixel data in response to a first clock signal; and second selection circuitry operable for receiving said second pixel data from said second source and third pixel data from an output of said first selection circuitry, said second selection circuitry being operable for selecting for outputting said second pixel data from said second source and said third pixel data from said output in response to a set of control signals.
