Abstract
In devices in which display data is read from a memory for display, display underflow in a processing block is alleviated by controlling a clock frequency driving the processing block. Stages of the processing block send underflow detection signals to underflow prevention logic. The underflow prevention logic controls the frequencies of clock signals generated by a clock generator to alleviate the underflow condition.
