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： 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： Code handling, such as interpreting language instructions or performing “just-in-time” compilation, is performed 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 mechanism is provided for configuring offline player behavior within a persistent world game. A player agent for an offline player includes an event monitor that 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 may generate game events on behalf of the offline player. The player agent may also receive messages from an offline player. The messages may include commands for adding, removing, or editing offline player rules. A message may also include a command to view a list of rules or fire a one-time execution of a rule upon receipt. Therefore, a player may contribute to the persistent virtual world even when offline by sending commands using a messaging client or Web browser.

摘要： A system and method are provided to dedicate one or more processors in a multiprocessing system to performing encryption functions. When the system initializes, one of the synergistic processing unit (SPU) processors is configured to run in a secure mode wherein the local memory included with the dedicated SPU is not shared with the other processors. One or more encryption keys are stored in the local memory during initialization. During initialization, the SPUs receive nonvolatile data, such as the encryption keys, from nonvolatile register space. This information is made available to the SPU during initialization before the SPUs local storage might be mapped to a common memory map. In one embodiment, the mapping is performed by another processing unit (PU) that maps the shared SPUs' local storage to a common memory map.
