    摘要： A system and method for specifying an access hint for prefetching limited use data. A processing unit receives a data cache block touch (DCBT) instruction having an access hint indicating to the processing unit that a program executing on the data processing system may soon access a cache block addressed within the DCBT instruction. The access hint is contained in a code point stored in a subfield of the DCBT instruction. In response to detecting that the code point is set to a specific value, the data addressed in the DCBT instruction is prefetched into an entry in the lower level cache. The entry may then be updated as a least recently used entry of a plurality of entries in the lower level cache. In response to a new cache block being fetched to the cache, the prefetched cache block is cast out of the cache.

    摘要： A method for implementing connected input/output (I/O) hub configuration and management includes configuring a first I/O hub in wrap mode with a second I/O hub. The hubs are communicatively coupled via a wrap cable. The method further includes generating data traffic on a computing subsystem that includes the hubs. Generating traffic includes: converting, via the first hub, a request to implement a transaction into an I/O device-readable request packet and transmitting the request packet over the wrap cable; converting, via the second hub, the I/O device-readable (IODR) request packet into a system readable request and transmitting the request over a system bus; converting, via the second hub, the response to an IODR response packet, and transmitting the response packet over the wrap cable; and converting, via the first hub, the IODR response packet into a system readable response packet, and transmitting the response packet over the system bus.

    摘要： A task obtained by a communications processor is decomposed into one or more requests that form a request group. The requests of the request group are sent to main memory and responses to those requests are expected. There may be requests for a plurality of request groups being processed concurrently. However, responses to the request groups are to be returned to the communications processor in the order in which the request groups were sent from the communications processor. To ensure this ordering, dependencies between the request groups are tracked by hardware coupled to the communications processor.

    摘要翻译： 由通信处理器获得的任务被分解成形成请求组的一个或多个请求。 请求组的请求被发送到主存储器，并且期望对这些请求的响应。 可能需要同时处理多个请求组的请求。 但是，请求组的响应将按照从通信处理器发送请求组的顺序返回给通信处理器。 为了确保这种排序，请求组之间的依赖关系由耦合到通信处理器的硬件进行跟踪。
