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 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： 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： The present invention is a method for integrating multiple object codes from heterogeneous architectures. For a program on a first processor to reference a program from the name space of a second processor, the object code for the second-processor program is enclosed in a wrapper to create object code in the first-processor name space. The header of the wrapped object code defines a new symbol in the name space of the first processor, and the symbol points to the second-processor object code contained in the wrapped object code. Instead of directly referencing the second-processor object code, the referencing program on the first processor references the wrapped object code. A system tool can be used to wrap the object code which runs on the second processor.
