摘要： A switching technique allows multiple interconnect bus devices to be connected to a single bus segment, even if the interconnect bus protocol only allows a one of the interconnect devices to be connected at any time. Each of the interconnect devices is connected to the interconnect bus segment with a switch, such that the interconnect device is electrically isolated from the interconnect bus segment when the switch is open. An interconnect sourcing agent connected to the interconnect bus segment controls the switches, closing the switch for one of the interconnect devices when a transaction is destined for that interconnect device, opening all of the other switches so that only one device is connected to the bus at any time.

摘要： A distributed direct memory access (DMA) architecture where greater than seven DMA channels are provided and utilized. Alternative methods are disclosed for paging or swapping DMA channels so that more than seven may exist in a computer system, but only seven may be available at a time to remain compatible with conventional DMA controller software. In one method, channels may be assigned identical addresses, with one enabled at one time. In another method, channels are assigned unique addresses but the DMA master addresses only a subset of the total number of channels so that up to seven are available to compatible software at any one time.

摘要： A distributed direct memory access (DMA) architecture where DMA controllers are modified to create isolated DMA channels. Each isolated channel includes its own set of uniquely addressable registers which provide functional compatibility with conventional DMA controllers. A DMA master interacts compatibly with the computer system and transparently communicates special cycles to the isolated DMA channels to cause the distributed DMA architecture to appear as the DMA controllers. The DMA master spawns special cycles to the isolated channels for sharing common write data with multiple channels and merging read data into a single DMA controller compatible register. Channel 4 cascading is also handled via tracking registers and special cycles to maintain disable and masking functionality of channel 4 as it effects channels 0-3.
摘要翻译：分布式直接存储器访问（DMA）架构，其中DMA控制器被修改以创建隔离的DMA通道。每个隔离通道都包括其自己的一组唯一可寻址寄存器，提供与常规DMA控制器的功能兼容性。 DMA主机与计算机系统兼容交互，并将特殊周期透明地传送到隔离的DMA通道，以使分布式DMA架构显示为DMA控制器。 DMA主机为隔离通道产生特殊周期，以共享具有多个通道的通用写入数据，并将读取数据合并到单个DMA控制器兼容寄存器中。通道4级联也通过跟踪寄存器和特殊周期来处理，以保持通道4的禁用和屏蔽功能，因为它影响通道0-3。

摘要： A hardware device interface supporting transaction authentication is described herein. At least some illustrative embodiments include a device, including an interconnect interface, and processing logic (coupled to the bus interface) that provides access to a plurality of functions of the device through the interconnect interface. A first transaction received by the device, and associated with a function of the plurality of functions, causes a request identifier within the first transaction to be assigned to the function. Access to the function is denied if a request identifier of a second transaction, subsequent to the first transaction, does not match the request identifier assigned to the function.

摘要： A system and method for remote direct memory access over a network switch fabric. Some illustrative embodiments may include a system comprising a first system node, a direct memory access (DMA) controller, a second system node, and a network switch fabric coupling together the first and second system nodes (the network switch fabric comprises a rooted hierarchical bus). The DMA controller is configured to perform a DMA transfer of data between the first and second system nodes across the network switch fabric. The data is formatted as one or more remote DMA (RDMA) protocol messages that are routed across the network switch fabric based on a bus end-device identifier corresponding to the second system node.
