摘要： A system and method for providing a persistent function server is provided. A multi-processor environment uses an interface definition language (idl) file to describe a particular function, such as an “add” function. A compiler uses the idl file to generate source code for use in marshalling and de-marshalling data between a main processor and a support processor. A header file is also created that corresponds to the particular function. The main processor includes parameters in the header file and sends the header file to the support processor. For example, a main processor may include two numbers in an “add” header file and send the “add” header file to a support processor that is responsible for performing math functions. In addition, the persistent function server capability of the support processor is programmable such that the support processor may be assigned to execute unique and complex functions.

摘要： A task queue manager manages the task queues corresponding to virtual devices. When a virtual device function is requested, the task queue manager determines whether an SPU is currently assigned to the virtual device task. If an SPU is already assigned, the request is queued in a task queue being read by the SPU. If an SPU has not been assigned, the task queue manager assigns one of the SPUs to the task queue. The queue manager assigns the task based upon which SPU is least busy as well as whether one of the SPUs recently performed the virtual device function. If an SPU recently performed the virtual device function, it is more likely that the code used to perform the function is still in the SPU's local memory and will not have to be retrieved from shared common memory using DMA operations.
摘要翻译：任务队列管理器管理与虚拟设备相对应的任务队列。当请求虚拟设备功能时，任务队列管理器确定SPU当前是否被分配给虚拟设备任务。如果已经分配了SPU，则该请求在SPU所读取的任务队列中排队。如果尚未分配SPU，则任务队列管理器将其中一个SPU分配给任务队列。队列管理器根据哪个SPU最不忙，以及一个SPU最近是否执行了虚拟设备功能来分配任务。如果SPU最近执行了虚拟设备功能，则用于执行该功能的代码更有可能仍在SPU的本地存储器中，并且不需要使用DMA操作从共享的公共存储器中检索。

摘要： A system and a method for sharing a common system memory by a main processor and a plurality of secondary processors. The sharing of the common system memory enables the sharing of data between the processors. The data are loaded into the common memory by the main processor, which divides the data to be processed into data blocks. The size of the data blocks is equal to the size of the registers of the secondary processors. The main processor identifies an available secondary processor to process the first data block. The secondary processor processes the data block and returns the processed data block to the common system memory. The main processor may continue identifying available secondary processors and requesting the available secondary processors to process data blocks until all the data blocks have been processed.

摘要： The present invention provides for notifying threads. A determination is made whether there is a condition for which a thread is to be notified. If so, a notification indicia is broadcasted. A flag is set in at least one memory storage area as a function of the notification indicia wherein the setting the flag occurs without the intervention of an operating system. Therefore, latencies for notification of threads are minimized.

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： An apparatus, a method, and a computer program product are provided for more efficiently allowing context switching. Currently, context switching can be costly because of both memory requirements to store data from pre-empted applications, as well as the bus requirements to move the data at pre-emption. To alleviate at least some of the costs associated with context switching, addition fields, either with associated Application Program Interfaces (APIs) or coupled to application modules, can be employed to indicate points of light weight context during the operation of an application. Therefore, an operating system can pre-empt applications at points where the context is relatively light, reducing the costs on both storage and on bus usage.

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 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 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 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.
