  • Methods, apparatuses and computer program products for simulating arbitrary unmodified code
    Patent number: 8170859
    Abstract: Arbitrary, unmodified code and/or software may be executed directly on a host processor operating in a virtualized mode using hardware virtualization support and performance counters.

  • Sharing a radio frequency interface resource
    Patent number: 8165631
    Abstract: Applications may seek access to a radio frequency interface resource on a processor-based system that exceeds the available capacity of that resource.
