摘要： An approach that uses a handler to detect asynchronous lock line reservation lost events, and switching tasks based upon whether a condition is true or a mutex lock is acquired is presented. A synergistic processing unit (SPU) invokes a first thread and, during execution, the first thread requests external data that is shared with other threads or processors in the system. This shared data may be protected with a mutex lock or other shared memory synchronization constructs. When requested data is not available, the SPU switches to a second thread and monitors lock line reservation lost events in order to check when the data is available. When the data is available, the SPU switches back to the first thread and processes the first thread's request.
摘要翻译：提出了一种使用处理程序来检测异步锁定线路保留丢失事件的方法，以及基于条件是真实还是获取互斥锁来切换任务。协同处理单元（SPU）调用第一个线程，并且在执行期间，第一个线程请求与系统中的其他线程或处理器共享的外部数据。该共享数据可以用互斥锁或其他共享内存同步结构来保护。当请求的数据不可用时，SPU切换到第二个线程并监视锁定线路保留丢失事件，以便检查数据可用时间。当数据可用时，SPU切换回第一个线程并处理第一个线程的请求。

摘要： Loading software on a plurality of processors is presented. A processing unit (PU) retrieves a file from system memory and loads it into its internal memory. The PU extracts a processor type from the file's header which identifies whether the file should execute on the PU or a synergistic processing unit (SPU). If an SPU should execute the file, the PU DMA's the file to the SPU for execution. In one embodiment, the file is a combined file which includes both PU and SPU code. In this embodiment, the PU identifies one or more section headers included in the file which indicates embedded SPU code within the combined file. In this embodiment, the PU extracts the SPU code from the combined file and DMA's the extracted code to an SPU for execution.
摘要翻译：在多个处理器上加载软件。处理单元（PU）从系统存储器检索文件并将其加载到其内部存储器中。 PU从文件头中提取一种处理器类型，用于标识文件是否应在PU或协同处理单元（SPU）上执行。如果SPU应该执行该文件，PU DMA将该文件提交给SPU执行。在一个实施例中，该文件是包括PU和SPU代码的组合文件。在该实施例中，PU识别包括在文件中的一个或多个区段标题，其指示组合文件内的嵌入式SPU代码。在本实施例中，PU从组合文件中提取SPU代码，并将提取的代码DMA提取给SPU以执行。

摘要： A computer system's multiple processors are managed 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： Grouping processors is presented. A processing unit (PU) initiates an application and identifies the application's requirements. The PU assigns one or more synergistic processing units (SPUs) and a memory space to the application in the form of a group. The application specifies whether the task requires shared memory or private memory. Shared memory is a memory space that is accessible by the SPUs and the PU. Private memory, however, is a memory space that is only accessible by the SPUs that are included in the group. When the application executes, the resources within the group are allocated to the application's execution thread. Each group has its own group properties, such as address space, policies (i.e. real-time, FIFO, run-to-completion, etc.) and priority (i.e. low or high). These group properties are used during thread execution to determine which groups take precedence over other tasks.
摘要翻译：介绍了分组处理器。处理单元（PU）启动应用程序并识别应用程序的要求。 PU以组的形式向应用分配一个或多个协同处理单元（SPU）和存储器空间。应用程序指定任务是否需要共享内存或专用内存。共享内存是可由SPU和PU访问的内存空间。然而，专用内存是只能由组中包含的SPU访问的内存空间。当应用程序执行时，组内的资源被分配给应用程序的执行线程。每个组都有自己的组属性，如地址空间，策略（即实时，FIFO，运行完成等）和优先级（即低或高）。在线程执行期间使用这些组属性来确定哪些组优先于其他任务。

摘要： A mechanism is provided for automatically waking a game client responsive to game events occurring within a persistent world online game. An event monitor monitors for events that occur in a persistent virtual world maintained by a game server. When a game event occurs that triggers an offline player rule, the player agent automatically activates execution of game client software. The player agent may also automatically log the player into the game server through the game client software. The player agent may generate and present a launcher dialog prompting the user whether to launch the game client software. Alternatively, the player agent may send a message to a messaging device of the offline player with instructions for launching the game client software remotely. Responsive to a message including a launch command, the player agent automatically launches the game client software on a game client device associated with the offline player.

摘要： A system and method for virtualization of processor resources is presented. A thread is created on a processor and the processor's local memory is mapped into an effective address space. In doing so, the processor's local memory is accessible by other processors, regardless of whether the processor is running. Additional threads create additional local memory mappings into the effective address space. The effective address space corresponds to either a physical local memory or a “soft” copy area. When the processor is running, a different processor may access data that is located in the first processor's local memory from the processor's local storage area. When the processor is not running, a softcopy of the processor's local memory is stored in a memory location (i.e. locked cache memory, pinned system memory, virtual memory, etc.) for other processors to continue accessing.

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.
