    摘要： Mechanisms are provided for processing an instruction in a processor of a data processing system. The mechanisms operate to receive, in a processor of the data processing system, an instruction, the instruction including power/performance tradeoff information associated with the instruction. The mechanisms further operate to determine power/performance tradeoff priorities or criteria, specifying whether power conservation or performance is prioritized with regard to execution of the instruction, based on the power/performance tradeoff information. Moreover, the mechanisms process the instruction in accordance with the power/performance tradeoff priorities or criteria identified based on the power/performance tradeoff information of the instruction.

    摘要： A mechanism is provided in a cache for providing a read and write aware cache. The mechanism partitions a large cache into a read-often region and a write-often region. The mechanism considers read/write frequency in a non-uniform cache architecture replacement policy. A frequently written cache line is placed in one of the farther banks. A frequently read cache line is placed in one of the closer banks. The size ratio between read-often and write-often regions may be static or dynamic. The boundary between the read-often region and the write-often region may be distinct or fuzzy.

    摘要： A technique for sharing a fabric to facilitate off-chip communication for on-chip units includes dynamically assigning a first unit that implements a first communication protocol to a first portion of the fabric when private fabrics are indicated for the on-chip units. The technique also includes dynamically assigning a second unit that implements a second communication protocol to a second portion of the fabric when the private fabrics are indicated for the on-chip units. In this case, the first and second units are integrated in a same chip and the first and second protocols are different. The technique further includes dynamically assigning, based on off-chip traffic requirements of the first and second units, the first unit or the second unit to the first and second portions of the fabric when the private fabrics are not indicated for the on-chip units.

    摘要： Mechanisms for accessing a set associative cache of a data processing system are provided. A set of cache lines, in the set associative cache, associated with an address of a request are identified. Based on a determined mode of operation for the set, the following may be performed: determining if a cache hit occurs in a preferred cache line without accessing other cache lines in the set of cache lines; retrieving data from the preferred cache line without accessing the other cache lines in the set of cache lines, if it is determined that there is a cache hit in the preferred cache line; and accessing each of the other cache lines in the set of cache lines to determine if there is a cache hit in any of these other cache lines only in response to there being a cache miss in the preferred cache line(s).
