    摘要: The present invention provides an optical communication method, comprising: performing modulation on the obtained bit stream data to generate modulated signals; performing differential encoding on the modulated signals to generate differentially encoded signals; converting the differentially encoded signals into electrical signals; and mapping the electrical signals onto optical carriers to generate optical signals for transmission. With the present invention, it is possible to enhance the system's capability of resisting inter-carrier interference without decreasing spectrum efficiency, hence improving the tolerance of existing optical communication systems towards laser linewidth, fast-changing PMD, optical fiber nonlinearity, inter-channel interference and other damages, greatly enhancing system performances.

    摘要: A multi-core system configured to execute a plurality of tasks and having a semaphore engine and a direct memory access (DMA) engine capable of selecting, by a task scheduler of a first core, a first task for execution by the first core. In response to a semaphore lock request, the task scheduler of the first core switches the first task to an inactive state and selects a next task for execution by the first core. After the semaphore engine acquires the semaphore lock of the first semaphore, a data transfer request is provided to the DMA engine. In response to the data transfer request, the DMA engine transfers data associated with the locked first semaphore to the entry of the workspace of the first core.

    摘要: A data processing system includes a processor core and a hardware module. The processor core performs tasks on data packets. The ordering scope manager stores a first value in a first storage location. The first value indicates that exclusive execution of a first task in a first ordering scope is enabled. In response to a relinquish indicator being received, the ordering scope manager stores a second value in the first storage location. The second value indicates that the exclusively execution of the first task in the first ordering scope is disabled.

    摘要: A method of multicast data transfer including accessing a source address to a source location of mapped memory which stores source data, accessing multiple destination addresses to corresponding destination locations of the mapped memory, and for each of at least one section of the source data, reading the section using the source address, storing the section into a local memory of a data transfer device, and writing the section from the local memory to each destination location in the mapped memory using the destination addresses. Separate source and destination attributes may be provided, so that the source and each destination may have different attributes for reading and storing data. The source and each destination may have any number of data buffers accessible by corresponding links provided in data structures supporting the data transfer. The source data may be divided into sections and handled section by section.
