摘要： A system and method is provided to deliver messages to processors operating in a multi-processing environment. In a multi-processor environment, interrupts are managed by storing events in a queue that correspond to a particular support processor. A main processor decodes an interrupt and determines which support processor generated the interrupt. The main processor then determines whether a kernel or an application should process the interrupt. Interrupts such as page faults, segment faults, and alignment errors are handled by the kernel, while “informational” signals, such as stop and signal requests, halt requests, mailbox requests, and DMC tag complete requests are handled by the application. In addition, multiple identical events are maintained, and event data may be included in the interrupt using the invention described herein.

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.

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 is provided to perform code handling, such as interpreting language instructions or performing “just-in-time” compilation using a heterogeneous processing environment that shares a common memory. In a heterogeneous processing environment that includes a plurality of processors, one of the processors is programmed to perform a dedicated code-handling task, such as perform just-in-time compilation or interpretation of interpreted language instructions, such as Java. The other processors request code handling processing that is performed by the dedicated processor. Speed is achieved using a shared memory map so that the dedicated processor can quickly retrieve data provided by one of the other processors.

摘要： A method and apparatus is provided for analyzing performance of a computer or data processing system, during the time that a specified task is running on the system. The analysis is used to furnish a system user with a list of proposed hardware component upgrades that would improve system performance in various respects, each being accompanied by a parameter value indicating the improvement a particular upgrade would provide. Usefully, listed upgrades are made available over the Internet, for purchase by system users. In an embodiment directed to a method, for use with a computer system comprising a configuration of hardware components, selected hardware components are monitored as the system performs a specified task. This is done to acquire statistics representing the operation of respective selected components. The statistics are processed, to identify at least one selected component that impedes the system in performing the task. An upgrade of the identified component is then proposed, together with an indication of the improvement that would result if the upgrade is made.

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 receiving system allows for the coherent detection of a spread-spectrum transmission at any point in time during the transmission, thereby avoiding the need to identify the start of the transmission during the transmission-detection process. An input buffer captures the transmissions on a communication channel using a moving time-window. A detector processes a time-slice from the input buffer and identifies all of the simultaneously transmitting transmitters during that time-slice. As each transmitter is identified, the demodulator traces back-in-time to identify where the message can first be detected in the input buffer. The transmission includes suitable characteristics to facilitate detection and demodulation of the message content, but need not contain a preamble to allow the detection process.
