ABSTRACT:
An LCD panel controller includes a panel display driver driving a display panel having an inherent line input buffer, a memory/interface block, a frame memory and a host computer. The memory interface block implements a non-uniform asynchronous transfer protocol for memory access and arbitration between requests for memory access by the display driver and one or more other interfaces shown in the memory/interface block. The nonuniform or asynchronous transfer provides a good level of memory access to other memory users, without requiring significant amounts of additional memory or significantly faster memory.
