    摘要： Some embodiments include, for example, devices, systems, and methods of handling transactions. In some demonstrative embodiments, an apparatus to handle transactions in a computing system may include a master unit to arbitrate between read and write requests to be issued over a request bus according to at least first and second arbitration schemes. A first ratio between read and write requests issued by the master unit according to the first arbitration scheme may be different from a second ratio between read and write requests issued by the master unit according to the second arbitration scheme.

    摘要： Embodiments herein provide a transaction level mechanism that ensures that the links are operational right in time for the data flow, so that the data flow will not be impacted by delays associated with link recovery into the operational state. The path has links that have the ability to be in an inactive mode or an active mode. The embodiments herein transmit an “activation transmission” over the path to turn on the links within the path, before sending a data transfer (comprising packetized data) to turn on (wake up) the inactive links within the path, so that the actual data transfer does not experience any such start-up or wake-up delays.

    摘要： A communications apparatus uses at least one logical communications link that comprises a plurality of lanes within a computerized hardware device. A data transfer monitor is connected to the logical communications link and measures the real-time data transfer bandwidth of the logical communications link. In addition, a link management unit or link width control unit (comparator) is connected to the lanes and to the data transfer monitor and continually compares the real-time data transfer bandwidth to a predetermined data transfer bandwidth standard. If the real-time data transfer bandwidth is below the predetermined data transfer bandwidth standard, the link management unit is adapted to perform up-configuring of the logical communications link by activating additional lanes up to a maximum number of lanes making up the logical communications link. Conversely, if the real-time data transfer bandwidth is above the predetermined data transfer bandwidth standard, the link management unit is adapted to perform down-configuring the logical communications link by deactivating lanes within the logical communications link. The lanes consume less power when the lanes are deactivated relative to when the lanes are activated, thus the down-configuring reduces power consumption.

    摘要翻译： 通信装置使用至少一个逻辑通信链路，其包括计算机化的硬件设备内的多条通道。 数据传输监视器连接到逻辑通信链路，并测量逻辑通信链路的实时数据传输带宽。 此外，链路管理单元或链路宽度控制单元（比较器）连接到通道和数据传输监视器，并将实时数据传输带宽连续地与预定的数据传输带宽标准进行比较。 如果实时数据传输带宽低于预定的数据传输带宽标准，则链路管理单元适于通过激活附加通道来执行逻辑通信链路的上配置，最多数目的通道组成逻辑通信链路 。 相反，如果实时数据传输带宽高于预定的数据传输带宽标准，则链路管理单元适于通过停用逻辑通信链路内的通道来执行逻辑通信链路的下配置。 当通道相对于通道被激活时，通道消耗较少的功率，因此下配置降低功耗。

    摘要： Optimization of a use of memory buffers of a device connected to a physical link including virtual channels (VCs) while sustaining bandwidth for communication between the device and another entity, by determining an initial allocation of memory buffers of each VC. Further, the optimization is accomplished by determining whether a next VC is active or inactive. If the VC is determined to be inactive, a number of memory buffers initially allocated to the inactive channel is determined, and the memory buffers are re-allocated between the active VCs.

    摘要： A mechanism for speculative packet transmission including a credit-based flow control interconnect device to initiate speculative transmission of a Transaction Layer Packet if the number of available flow control (FC) credits is insufficient for completing the transmission. The sending device initiates a speculative transmission of packets to the receiving device even though the packet for transmission requires a number of FC credits greater than the available FC credits. If the additional FC credits required to complete the packet transmission become available to the sending device before the transmission is completed, the packets are then fully transmitted by the sending device. Otherwise, if the additional FC credits required do not become available prior to completion of the transmission, then the sending device aborts the transmission without utilization of the FC credits. The sending device may initiate speculative packet transmission only if a particular minimal amount of FC credits is available.

    摘要翻译： 一种用于推测分组传输的机制，包括基于信用的流控制互连设备，用于如果可用流控制（FC）信用的数量不足以完成传输，则启动事务层分组的推测传输。 发送设备发起分组到接收设备的推测传输，即使用于传输的分组需要大于可用FC信用的多个FC信用。 如果完成分组传输所需的附加FC信用在发送完成之前对发送设备可用，则发送设备将完全发送分组。 否则，如果在完成传输之前所​​需的附加FC信用不可用，则发送设备在不使用FC信用的情况下中止传输。 只有当特定的最小量的FC信用可用时，发送设备才能启动推测性分组传输。
