Abstract
A display controller includes a processor arranged to process executable instructions and associated data, a single memory device for storing the executable instructions and associated data and EDID corresponding to the display device that is always available for access by the data ports and/or the processor regardless of a power state of the display controller, a data buffer for storing EDID read from the memory device, and an arbitration circuit for arbitrating memory device access requests between the processor and a requesting data port wherein when the data buffer is not almost empty, then the arbitration circuit grants the processor access to the memory wherein when the data buffer is almost empty, then the arbitration circuit grants only the requesting data port access to them memory so as to replenish the data buffer with read EDID.
