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

A system and method for managing access to a shared resource employs mutually exclusive flags. The flags enable arbitration between all applications requesting the use of the shared resource and ensure that each application has exclusive and continuous use of the shared resource. The preferred embodiment uses hardware to realize the flags and the flag arbitrating means. In one embodiment, the applications control and observe the flags through read/write registers. Alternative embodiments provide a unique read/write register for each application using the shared resource.
