    Abstract: A computer processor includes a decoder for decoding machine instructions and an execution unit for executing those instructions. The decoder and the execution unit are capable of decoding and executing vector instructions that include one or more format conversion indicators. For instance, the processor may be capable of executing a vector-load-convert-and-write (VLoadConWr) instruction that provides for loading data from memory to a vector register. The VLoadConWr instruction may include a format conversion indicator to indicate that the data from memory should be converted from a first format to a second format before the data is loaded into the vector register. Other embodiments are described and claimed.

    Abstract: A method and apparatus to execute data speculative instructions in a processor comprising at least one source register, each source register comprising a bit to indicate validity of data in the at least one source register. A data validity circuit coupled to the one or more source registers to determine the validity of the data in the source registers, and to indicate the validity of the data in a destination register based upon the validity bit in the at least one source register. The processor optionally comprising a checker unit to retire those instructions from the execution unit which write valid data to the destination register, and to re-schedules those instructions for execution which write invalid data to the destination register.

    Abstract: A method and apparatus for efficiently caching streaming and non-streaming data is described herein. Software, such as a compiler, identifies last use streaming instructions/operations that are the last instruction/operation to access streaming data for a number of instructions or an amount of time. As a result of performing an access to a cache line for a last use instruction/operation, the cache line is updated to a streaming data no longer needed (SDN) state. When control logic is to determine a cache line to be replaced, a modified Least Recently Used (LRU) algorithm is biased to select SDN state lines first to replace no longer needed streaming data.

    Abstract translation: 本文描述了用于有效地高速缓存流和非流数据的方法和装置。 诸如编译器的软件识别最后使用的流指令/操作，这些指令/操作是用于访问多个指令或一定时间量的最后指令/操作来访问流数据。 作为执行对最后使用指令/操作的高速缓存线的访问的结果，将高速缓存行更新为不再需要的流数据（SDN）状态。 当控制逻辑要确定要替换的高速缓存行时，修改的最近最少使用（LRU）算法被偏置以首先选择SDN状态行来替换不再需要的流数据。
