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 address translator and a method for translating a linear address into a physical address for memory management in a computer is described herein. Different memory sizes, and different page sizes can be selected. The address translator can translate from a standard 32-bit linear address for compatibility with previous 32-bit architectures, and can also translate to a physical memory size with a larger physical address than linear address; i.e., greater than 32 bits (e.g. 36 bits and up), with no increase in access time. The address translator translates a linear address that includes an offset and a plurality of fields used to select entries in a plurality of tables. The format of the linear address into fields is dependent upon the selected memory size and the selected page size. For a large memory size, the tables include a directory pointer table that includes a group of directory pointers, a plurality of page table directories each of which includes a group of page directory entries, and a plurality of page tables each of which includes a group of page table entries. The size of the entries in the tables is dependent upon the selected memory size. The contents of the tables are stored in memory, and furthermore the pointer table is stored in both main memory and in dedicated pointer table registers.
摘要翻译：这里描述了地址转换器和用于将线性地址翻译成用于计算机中的存储器管理的物理地址的方法。可以选择不同的内存大小和不同的页面大小。地址转换器可以从标准的32位线性地址转换，以兼容以前的32位体系结构，并且还可以转换为具有比线性地址更大的物理地址的物理内存大小; 即大于32位（例如36位及以上），而不增加访问时间。地址转换器翻译包括用于选择多个表中的条目的偏移和多个字段的线性地址。线性地址到字段的格式取决于所选的内存大小和所选的页面大小。对于大的存储器大小，表包括目录指针表，其包括一组目录指针，多个页表目录，每个页表目录包括一组页目录条目，以及多个页表，每个页表包括一组的页表条目。表中条目的大小取决于所选的内存大小。表的内容存储在存储器中，此外，指针表存储在主存储器和专用指针表寄存器中。
