ABSTRACT:
Display data read out from a picture display memory region within a UMA memory is written in a FIFO, and display data is transferred from the FIFO at a timing required by a liquid crystal panel, wherein a timing of reading out display data from the UMA region and a timing of transferring display data to the liquid crystal panel are made asynchronous to each other. Also, upon detection of writing in a display data region, display data for one picture frame is transferred to the liquid crystal panel, whereby the reduction in the bandwidth for CPU's memory accesses to the UMA is prevented, and the reduction in the overall power consumption of the display system is realized.
