摘要： Memory controllers, systems, methods, and computer-readable mediums for applying a page management policy(ies) based on stream transaction information are disclosed. In one embodiment, a memory controller is provided and configured to receive memory access requests for stream transactions. The memory controller is configured to perform a memory access to a memory page(s) in memory included in the stream transaction. The controller is further configured to apply a page management policy(ies) to the memory page(s) in memory based on information related to the stream transactions. In this manner, the page management policy(ies) can be configured to utilize page open policies for efficiency that stream transactions may facilitate, but while also recognizing and taking into consideration in the page management policy latency issues that can arise when the memory controller is handling memory access requests from different devices.

摘要： Devices, systems, methods, and computer-readable mediums for arbitrating stream transactions based on information related to the stream transactions are disclosed. A stream transaction is a superset of burst access types to facilitate efficient bulk transfers of data. In one embodiment, an arbiter is provided that arbitrates bus transactions between a plurality of devices coupled to a bus competing for resources accessible through the bus. To efficiently arbitrate stream transactions requested on the bus, the arbiter is configured to use information related to the stream transactions to provide a view of future bus traffic on the bus. The arbiter is configured to use this stream transaction information to apply bus arbitration policies for arbitrating stream transactions. In this example, the bus arbitration policy can be adjusted for stream transactions based on the stream transaction information, if necessary, for the arbiter to attempt to meet a parameter(s) for completing the stream transactions.

摘要： Efficient techniques are described for identifying active interrupt requests to improve performance and reduce power requirements in a processor system. A method to identify active sampled interrupt requests begins with scanning groups of the sampled interrupt requests one group at a time to identify an active interrupt request in any scanned group. A group of interrupt requests is an M/R priority of N sampled interrupt requests, M is the number of priority levels, and R is a resource sharing factor. A group selection circuit is updated to a new group in response to having identified an active interrupt request to improve the latency in processing high priority interrupt requests. Also, groups having active interrupt requests may be identified by early detection or look ahead circuitry. The scanning of groups of interrupt requests may be stopped until the next interrupt request sample point has been reached to reduce power utilization.

摘要： Systems and methods for trace multicast across a bus structure are provided. Preferably, the bus structure is that of a System-on-a-Chip (SoC), where the SoC includes a number of master components and a number of slave components connected via the bus structure. The bus structure supports a trace multicast feature. In one embodiment, the bus structure receives a bus transaction from a master component and, in response, outputs the bus transaction to a corresponding slave port. In addition, the bus structure determines whether a trace multicast is desired for the bus transaction. If a trace multicast is desired, the bus structure generates an additional bus transaction having one or more transaction attributes that include a translated version of the bus transaction and outputs the additional bus transaction to a trace slave port of the bus structure. The trace multicast feature provides a non-invasive mechanism for driver-level trace.
摘要翻译：提供了通过总线结构跟踪组播的系统和方法。优选地，总线结构是片上系统（SoC）的结构，其中SoC包括多个主组件和通过总线结构连接的多个从组件。总线结构支持跟踪组播功能。在一个实施例中，总线结构从主组件接收总线事务，并且作为响应，将总线事务输出到对应的从端口。此外，总线结构确定对于总线事务是否需要跟踪多播。如果需要跟踪多播，则总线结构生成具有一个或多个事务属性的附加总线事务，该事务属性包括总线事务的转换版本，并将附加总线事务输出到总线结构的跟踪从站端口。跟踪多播功能为驱动程序级跟踪提供了非侵入性机制。
