ABSTRACT:
The present invention relates to the generation of display identification (ID) information in a computer display system. The display ID generator includes a memory which stores display ID information. A control logic device couples the information from the memory to a first FIFO. A state machine accesses the information held in the first FIFO and determines the duration information. Next, the state machine couples the information to a second FIFO. Last, the information in the second FIFO is coupled to a third memory and a sequential counter. After initial loading of information in second memory and sequential counter, the sequential counter determines when second memory and itself will be loaded with the next set of information. Once the sequential counter reaches zero, it generates a signal enabling itself and the second memory to load the next set of information.
