This is a video pattern generator which can be used for testing video displays. It currently supports four patterns; horizontal lines, vertical lines, moving horizontal lines, and moving vertical lines. It sends out 1 pixel every clock cycle and forms the pattern on the fly using counters. This module has been used sucessfully to test a Camera Link serializer, SDXC Card video streamer and video rotator.
