    • In one embodiment, a method for controlling an instruction cache including a least-recently-used bits array, a tag array, and a data array, includes looking up, in the least-recently-used bits array, least-recently-used bits for each of a plurality of cacheline sets in the instruction cache, determining a most-recently-used way in a designated cacheline set of the plurality of cacheline sets based on the least-recently-used bits for the designated cacheline, looking up, in the tag array, tags for one or more ways in the designated cacheline set, looking up, in the data array, data stored in the most-recently-used way in the designated cacheline set, and if there is a cache hit in the most-recently-used way, retrieving the data stored in the most-recently-used way from the data array.

    • A bus expander bridge is provided for interfacing first and second external buses (such as PCI buses) to a third bus. The bus expander bridge is configurable in either an independent mode in which the first and second external buses operate independently and a combined mode in which the first and second external buses are combined to create a single bus. The bus expander bridge includes a first set of data queues for routing data between the first external bus and the third bus, and a second set of data queues for routing data between the second external bus and the third bus. The bus expander bridge also includes a controller coupled to the first and second sets of data queues and operating the first and second sets of data queues in parallel for the independent mode. The controller routes even addressed data through the first set of data queues and routes odd addressed data through the second set of data queues for the combined mode.
    • 提供一个总线扩展器桥接器用于将第一和第二外部总线(例如PCI总线)与第三总线接口。 总线扩展器桥可以以独立模式配置,其中第一和第二外部总线独立运行,以及组合模式,其中组合第一和第二外部总线以创建单个总线。 总线扩展器桥包括用于在第一外部总线和第三总线之间路由数据的第一组数据队列,以及用于在第二外部总线和第三总线之间路由数据的第二组数据队列。 总线扩展器桥还包括耦合到第一和第二组数据队列的控制器,并且为独立模式并行地操作第一和第二组数据队列。 控制器通过第一组数据队列路由寻址数据,并通过组合模式的第二组数据队列路由奇数寻址数据。
