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： 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： A processing system is disclosed with a sending component and a receiving component connected by a bus. The bus may be configured with first and second channels. The sending component may be configured to broadcast on the first channel read and write address information, read and write control signals, and write data. The sending component may also be configured to signal the receiving component such that the receiving component can distinguish between the read and write address information, the read and write control signals, and the write data broadcast on the first channel. The receiving component may be configured to store the write data broadcast on the first channel based on the write address information and the write control signals, retrieve read data based on the read address information and the read control signals, and broadcast the retrieved read data on the second channel.

摘要： A DMA Controller, in response to a data transfer request from a slave device, initiates a memory transfer cycle and informs the slave device when the data transfer has completed. In order to avoid dead clock cycles on internal bus(es), the DMA Controller initiates a speculative data transfer cycle after the notification. The DMA Controller aborts the speculative data transfer cycle if the slave device does not request another data transfer within a predetermined time.

摘要： A processing system is disclosed with a sending component and a receiving component connected by a bus. The bus may be configured with transmit and receive channels. The transmit channel may have a plurality of sub-channels. The sending component may be configured to broadcast on each of the sub-channels information comprising read and write address locations, read and write control signals, and write data on each of the sub-channels. The receiving component may be configured to store the write data and retrieve read data in response to the information broadcast on any of the sub-channels, and broadcast the retrieved read data on the receive channel to the sending component. The sending component may further be configured to provide to the receiving component independent signaling for each of the sub-channels, the independent signaling being sufficient to allow the receiving component to determine the type of information broadcast on each of the sub-channels.
