ABSTRACT:
One embodiment of the present invention sets forth a protocol for packing and transferring pixel data between integrated circuits. The data transfer protocol may be used between a graphics processing unit and a video output encoder unit. The data transfers may include up to 20 pixels per arbitration cycle. By packing pixel data for transfer over a bus with a relatively small set of output pins, overall package pin count is reduced, while maintaining sufficient bandwidth to carry the pixel data the output pins. By moving the analog circuitry to a separate device, linked to the GPU via the bus, noise from the GPU may be effectively mitigate through physical separation.
