    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 method for controlling bandwidth in a direct memory access (DMA) unit of a computer processing system, the method comprising: assigning a DMA job to a selected DMA engine; starting a source timer; and issuing a request to read a next section of data for the DMA job. If a sufficient amount of the data was not obtained, allowing the DMA engine to wait until the source timer reaches a specified value before continuing to read additional data for the DMA job.

    摘要: A data processing system employs an improved arbitration process in selecting pending memory access requests received from the one or more processor cores for servicing by the memory. The arbitration process uses memory timing and state information pertaining both to memory access requests already submitted to the memory for servicing and to the pending memory access requests which have not yet been selected for servicing by the memory. The memory timing and state information may be predicted memory timing and state information; that is, the component of the data processing system that implements the improved scheduling algorithm may not be able to determine the exact point in time at which a memory controller initiates a memory access for a corresponding memory access request and thus the component maintains information that estimates or otherwise predicts the particular state of the memory at any given time.

    摘要: A data processing device includes an interconnect controller operable to manage the communication of information between modules of the data processing device via an interconnect. In response to a transaction request the interconnect controller selects a tag value from a set of available tag values, assigns the tag to the transaction and reserves the tag value so that it is unavailable for assignment to other transactions. If an expected response to the transaction request is not received within a designated amount of time, the transaction enters a timed-out state and the interconnect controller locks the tag value, so that it remains unavailable for assignment to other transactions until an unlock event, such as a request from software.

    摘要: Techniques have been developed to introduce processor core functional pattern tests into a memory space addressable by at least one processor core of an integrated circuit. In general, such functional pattern tests can include both instruction sequences and data patterns and, in some embodiments in accordance with the present invention, are introduced (at least in part) into on-chip cache memory using facilities of an on-chip loader. Instruction opcodes used in functional test sequences may be efficiently introduced into a plurality of target locations in memory (e.g., at locations corresponding to multiple interrupt handlers or at locations from which a multiplicity of cores execute their functional tests) using facilities of the on-chip loader. In some embodiments, instruction selections together with a base address, extent and stride indications may be used to direct operation of the on-chip loader. Likewise, data patterns used in the functional test sequences may be specified as a data pattern selection together with base address, extent and optional stride indications and introduced into a plurality of target memory locations using facilities of the on-chip loader. In some embodiments, other forms or encodings of directives may be used.

    摘要: Techniques have been developed to facilitate concurrent evaluation of hash rule entries in ways that allow an implementation to maintain a deterministic resultant hash irrespective of variations in the allocation of particular rules to particular storage banks or evaluation logic, such as may occur with rule set revisions. Similarly, uniform deterministic hash results can be assured even across a range of implementations that support greater or lesser levels of concurrent rule evaluations.

    摘要: A method includes storing a first transaction entry to a first software configurable storage location, storing a second transaction entry to a second software configurable storage location, determining that a first transaction indicated by the first transaction entry has occurred, determining that a second transaction indicated by the second transaction entry has occurred subsequent to the first transaction, and, in response to determining that the first transaction occurred and the second transaction occurred, storing at least one transaction attribute captured during at least one clock cycle subsequent to the second transaction. The first and second software configurable storage locations may be located in a trace buffer, where the at least one transaction attribute is stored to the trace buffer and overwrites the first and second transaction attributes. Each transaction entry may include a dead cycle field, a consecutive transaction requirement field, and a last entry field.
