Methods and apparatus for providing additional storage, in the form of a hardware assisted stack, usable by software running an environment with limited resources. As an example, the hardware assisted stack may provide additional stack space to VBIOS code that is accessible within its limited allocated address space.

System and method for hardware assisted stack

Methods, circuits, and apparatus for changing a frequency of a clock signal provided to a graphics memory while reducing any resulting visual glitch or disturbance on a monitor. A specific embodiment provides multiple clock sources that may be multiplexed or selected to provide a memory clock signal to the graphics memory. The multiplexer switches from providing a first clock source signal as the memory clock signal to providing a second clock source signal as the memory clock signal. The first clock source changes its frequency of operation. After the first clock source settles or stabilizes, the multiplexer switches back to providing the first clock source signal as the memory clock signal.

Dynamic memory clock adjustments

Method of providing a second clock while changing a first supplied clock frequency then supplying the changed first clock

A graphics processing unit, which includes a clock generator configured to generate a clock signal and a controller coupled to the clock generator. The controller is configured to receive the clock signal, compare the clock signal with a synchronization signal to generate a timing signal, and transmit the timing signal to a second graphics processing unit connected to the graphics processing unit.
