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 a scheduler to schedule pending memory access requests and a memory controller to service scheduled pending memory access requests. The memory access requests are asynchronously scheduled with respect to the clocking of the memory. The scheduler is operated using a clock signal with a frequency different from the frequency of the clock signal used to operate the memory controller. The clock signal used to clock the scheduler can have a lower frequency than the clock used by a memory controller. As a result, the scheduler is able to consider a greater number of pending memory access requests when selecting the next pending memory access request to be submitted to the memory for servicing and thus the resulting sequence of selected memory access requests is more likely to be optimized for memory access throughput.
摘要翻译：数据处理系统使用调度器来调度待执行的存储器访问请求和存储器控制器来服务预定的未决存储器访问请求。存储器访问请求相对于存储器的时钟被异步调度。使用频率不同于用于操作存储器控制器的时钟信号的频率的时钟信号来操作调度器。用于时钟调度器的时钟信号的频率可能低于存储器控制器使用的时钟频率。因此，当选择要提交给存储器进行服务的下一个未决的存储器访问请求时，调度器能够考虑更多数量的待处理存储器访问请求，因此所选择的存储器访问请求的结果序列更有可能被优化用于内存访问吞吐量。

摘要： Techniques have been developed to facilitate evaluation of match and hash rule entries in ways that allow an implementation to decouple (i) the order in which match rules are applied to a first subset of packet header fields from (ii) the ordering of a second subset of packet header fields over which a non-commutative hash is computed. In short, the set and ordering of fields evaluated in accordance with a precedence order of rules need not correspond to the set or ordering of fields over which a hash is computed in a communications controller.
