  • Devices, methods and computer program products for reverse execution of a simulation
    Patent number: 8276127
    Abstract: Devices, methods, and software program products for reverse execution of a simulation and/or tracing a value are provided. A state of a preceding checkpoint may be restored and a simulation may be run forward. Break points or watch points may be noted and the state of the last occurring breakpoint or watch point preceding the current simulation position may be restored. If no breakpoint or watch point occurred, an earlier checkpoint may be loaded and the previous steps may be repeated.
    Type: Grant

    Date of Patent: September 25, 2012
    Assignee: Intel Corporation
    Inventors: Samuel Rydh, Peter S. Magnusson, Bengt Werner
  • 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. The arbitrary software may be run on the host processor until the host processor exits from the virtualized mode. An end execution time may be calculated in response to the host processor exiting from the virtualized mode. An event may then be handled based on an execution time at which the host processor exited from the virtualized mode and a time at which a scheduled event was to occur.
