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 sharing resources between real-time and virtualizing operating systems is presented. A computer system uses effective address mapping of support processors' local memory to share resources between separate operating systems. When threads are created for either operating system, the thread's corresponding processor memory is mapped into an effective address space. In doing so, the processor's local memory is accessible by the thread, regardless of whether the processor is running, or whether the processor is executing a different thread from a different operating system. For example, a computer system may have eight support processors and running two operating systems whereby the first operating system requires six support processors and the second operating system requires all eight support processors. In this example, resources are virtualized and shared between the two operating systems in order to meet the requirements of both operating systems.
摘要翻译：介绍了一种在实时和虚拟化操作系统之间共享资源的系统和方法。计算机系统使用支持处理器的本地存储器的有效地址映射来在不同的操作系统之间共享资源。当为任一操作系统创建线程时，线程的相应处理器内存映射到有效的地址空间。在这样做时，处理器的本地内存可由线程访问，无论处理器是否在运行，还是处理器是否正在从不同的操作系统执行不同的线程。例如，计算机系统可以具有八个支持处理器并且运行两个操作系统，由此第一操作系统需要六个支持处理器，而第二操作系统需要所有八个支持处理器。在这个例子中，为了满足两个操作系统的要求，在两个操作系统之间虚拟化和共享资源。

摘要： A system and method for 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：提出了一种用于分组处理器的系统和方法。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 system and method for 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： A system and method for asynchronously traversing a disjoint linked data structure is presented. A synergistic processing unit (SPU) includes a handler that works in conjunction with a memory flow controller (MFC) to traverse a disjoint linked data structure. The handler compares a search value with a node value, and provides the MFC with an effective address of the next node to traverse based upon the comparison. In turn, the MFC retrieves the corresponding node data from system memory and stores the node data in the SPU's local storage area. The MFC stalls processing and sends an asynchronous event interrupt to the SPU which, as a result, instructs the handler to retrieve and compare the latest node data in the local storage area with the search value. The traversal continues until the handler matches the search value with a node value or until the handler determines a failed search.
摘要翻译：提出了一种用于异步遍历不相交的数据结构的系统和方法。协同处理单元（SPU）包括与存储器流控制器（MFC）一起工作的处理程序，以遍历不相交的数据结构。处理程序将搜索值与节点值进行比较，并根据比较为MFC提供下一个节点的有效地址进行遍历。反过来，MFC从系统存储器检索相应的节点数据，并将节点数据存储在SPU的本地存储区域中。 MFC停止处理并向SPU发送异步事件中断，结果指示处理程序检索和比较本地存储区域中的最新节点数据与搜索值。遍历继续，直到处理程序与搜索值与节点值匹配，或者直到处理程序确定失败的搜索。

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 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.
