Abstract: A system, method, and computer program product for recovering from a memory underflow condition associated with generating video signals are disclosed. The method includes the steps of determining that a first counter is greater than a second counter, incrementing an address corresponding to a memory fetch request by an offset, and issuing the memory fetch request to a memory. The first counter represents a number of pixels that have been read by a display pipeline for a current frame and the second counter represents a number of pixels requested from a memory for the current frame.
