摘要： The present invention teaches a new system for transferring data between a network and hosts coupled to the network. The system uses an adapter, that is coupled between the host and the network, to allow segmenting and reassembling cells directly in the host memory. The present invention also teaches a pipelined DMA architecture to overcome the problem of the interruption of the DMA operation when switching from one virtual circuit to the next. This architecture depends on fast access to a local memory used for storing buffer descriptors for each virtual circuit. In this architecture, a two stage pipeline is used with the first stage performing the local memory access while the second stage performs the DMA transfers. When the pipeline is filled, both stages will operate in parallel yielding significant gain in performance due to continuous operation of the DMA.
摘要翻译：本发明教导了一种用于在网络和耦合到网络的主机之间传送数据的新系统。该系统使用耦合在主机和网络之间的适配器，以允许在主机存储器中直接分割和重新组合单元。本发明还教导了流水线DMA结构，以克服当从一个虚拟电路切换到下一个虚拟电路时DMA操作中断的问题。该架构取决于快速访问用于存储每个虚拟电路的缓冲区描述符的本地存储器。在该架构中，使用两级流水线，第一级执行本地存储器访问，而第二级执行DMA传输。当管道填满时，由于DMA的连续运行，两个阶段将并行运行，从而产生显着的性能增益。

摘要： An input/output processor architecture for providing an interface between peripheral subsystems and a generalized data processor. The interface processor enables data to be transferred between two address spaces (the generalized data processor address space and an external processor I/O address space) by mapping a portion of the I/O address space into a portion of the GDP address space. This mapping facility provides the peripheral subsystem with a "window" into the associated GDP subsystem. It accepts addresses within a certain subrange, or subranges, and translates them into references into one or more GDP data segments.A function-request facility provides a functional capability over certain objects within the GDP address space.The two facilities provide software on an external processor with a window into the address space of the GDP that enables the software, via the function request means, to send messages to and receive messages from the GDP and to manipulate an environment provided for the external processor within its address space.
