ABSTRACT:
A graphics processor is provided. The graphics processor includes a memory storing image data for presentation and a display memory region in communication with the memory, the display memory region supplying image data to a display panel for presentation. The graphics processor includes bandwidth control logic configured to monitor a lag between an output from the display memory region and an input into the display memory region. The bandwidth control logic is further configured to prevent a level of the display memory from decrementing when the lag between the output and the input is capable of causing corruption on the display panel due to a lack of data from the display memory region. A method for avoiding a buffer under run and a device are included.
