    摘要： A system and method is provided to improve software simulation. A software emulator is used in conjunction with a hardware simulator. A special snapshot instruction is included in the software code that is emulated. When the snapshot instruction is encountered, values such as register, memory, and program stack values, are stored creating an initial snapshot. Code continues to be emulated and, when the next snapshot instruction is encountered, the values are written to create a second snapshot. The initial values are used to set an initial state in a hardware model that is simulated on a hardware simulator. The results of the hardware simulation are compared to the second snapshot to uncover software errors and/or hardware errors so that the software can be modified or the hardware design can be modified. Multiple sets of snapshots can be taken to analyze multiple sections of the software program.

    摘要： A computer implemented method, data processing system, and computer usable code are provided for using software and hardware thermal profiles to schedule the execution of applications. Hardware and software thermal profiles are generated for a set of processors and a set of applications, respectively, to form a plurality of hardware and software thermal profiles. Then a set of hardware and software thermal profiles are selected from the plurality of hardware and software thermal profiles. The set of software thermal profiles and the set of hardware thermal profiles are used to generate a thermal index. Finally, the execution of the set of applications is scheduled using the thermal index.

    摘要： A method and a system for managing a computer system's multiple processors as devices. The operating system accesses the multiple processors using processor device modules loaded into the operating system to facilitate a communication between an application requesting access to a processor and the processor. A device-like access is determined for accessing each one of the processors similar to device-like access for other devices in the system such as disk drives, printers, etc. An application seeking access to a processor issues device-oriented instructions for processing data, and in addition, the application provides the processor with the data to be processed. The processor processes the data according to the instructions provided by the application.

    摘要： A system and method for using a processor thread as a debugger is presented. A computer system boots up and initiates a debugger thread. The debugger thread loads a robust, debugger operating system and executes the debugger operating system. Once the debugger thread is functioning, the debugger thread invokes an operational thread. In turn, the operational thread loads a primary operating system and may run various applications. While the operational thread executes the primary operating system and the applications, the debugger thread monitors the operational thread for proper functionality. When the operational thread crashes or terminates, the debugger thread retrieves operational data from the operational thread and provides the operational data to a software developer for analysis.

    摘要： A system and method for an asymmetric heterogeneous multi-threaded operating system are presented. A processing unit (PU) provides a trusted mode environment in which an operating system executes. A heterogeneous processor environment includes a synergistic processing unit (SPU) that does not provide trusted mode capabilities. The PU operating system uses two separate and distinct schedulers which are a PU scheduler and an SPU scheduler to schedule tasks on a PU and an SPU, respectively. In one embodiment, the heterogeneous processor environment includes a plurality of SPUs. In this embodiment, the SPU scheduler may use a single SPU run queue to schedule tasks for the plurality of SPUs or, the SPU scheduler may use a plurality of run queues to schedule SPU tasks whereby each of the run queues correspond to a particular SPU.

    摘要： A system and method for a processor thread acting as a system service provider is presented. A computer system boots up and initiates a service thread. The service thread is responsible for service related tasks, such as ECC checks and hardware log error checks. The service provider invokes a second thread which is used as an operational thread. The operational thread loads an operating system, a kernel, and runs various applications. While the operational thread executes, the service thread monitors the operational thread for proper functionality as well as monitoring service events. When the service thread detects a problem with either one of the service events or the operational thread, the service thread may choose to store operational data corresponding to the operational thread and terminates the operational thread.
