Abstract
Some embodiments include a graphics processing with thermal management capabilities. The graphics processing unit may include a display controller, a microprocessing engine coupled to the display controller, and a clock circuit coupled to the display controller and the microprocessing engine. The clock circuit may further include a raw clock signal coupled to the display controller, a divider coupled to the raw clock signal, and a multiplexer coupled to the divider. The divider may generate a divided version of the raw clock signal, which may be coupled to the multiplexer along with the raw clock signal. The multiplexer may selectively provide the raw clock signal and/or the divided version of the clock signal to the microprocessing engine such that the microprocessing engine may receive a timing signal that is independent of operations of the graphics processing unit and result in fewer glitches.
