    • A method and apparatus are provided for performing address translation in an input/output (I/O) expansion bridge. The I/O expansion bridge includes a first interface unit, a second interface unit, and an address translation unit. The first interface unit is configured to be coupled to a system memory and I/O controller through one or more I/O ports. The first interface unit enables data transfers over the one or more I/O ports to or from the main memory of a computer system. The second interface unit provides bus control signals and addresses to enable data transfers over a bus to or from a peripheral device. The address translation unit is coupled to the first interface unit and the second interface unit. The address translation unit translates addresses associated with transactions received on the second interface by accessing a local memory containing physical addresses of pages in the main memory of the computer system.
    • 提供了一种用于在输入/输出(I / O)扩展桥中执行地址转换的方法和设备。 I / O扩展桥包括第一接口单元,第二接口单元和地址转换单元。 第一接口单元被配置为通过一个或多个I / O端口耦合到系统存储器和I / O控制器。 第一接口单元能够通过一个或多个I / O端口将数据传输到计算机系统的主存储器或从计算机系统的主存储器进行数据传输 第二接口单元提供总线控制信号和地址以实现通过总线向/从外围设备传输数据。 地址转换单元连接到第一接口单元和第二接口单元。 地址转换单元通过访问包含计算机系统的主存储器中的页面的物理地址的本地存储器来转换与在第二接口上接收的交易相关联的地址。
