摘要： A processor core that includes a hardware decode unit to decode a vector frequency compress instruction that includes a source operand and a destination operand. The source operand specifying a source vector register that includes a plurality of source data elements including one or more runs of identical data elements that are each to be compressed in a destination vector register as a value and run length pair. The destination operand identifies the destination vector register. The processor core also includes an execution engine unit to execute the decoded vector frequency compress instruction which causes, for each source data element, a value to be copied into the destination vector register to indicate that source data element's value. One or more runs of the source data elements equal are encoded in the destination vector register as the predetermined compression value followed by a run length for that run.

摘要： An apparatus and method is described herein for providing speculative escape instructions. Specifically, an explicit non-transactional load operation is described herein. During execution of a speculative code region (e.g. a transaction or critical section) loads are normally tracked in a read set. However, a programmer or compiler may utilize the explicit non-transactional read to load from a memory address into a destination register, while not adding the read/load to the transactional read set. Similarly, a non-transactional store is also provided. Here, a transactional store is performed and not added to a write set during speculative code execution. And the store may be immediately globally visible and/or persistent (even after an abort of the speculative code region). In other words, speculative escape operations are provided to ‘escape’ a speculative code region to perform non-transactional memory accesses without causing the speculative code region to abort or fail.
摘要翻译：这里描述了一种用于提供推测逃逸指令的装置和方法。具体地，本文描述了显式的非事务性加载操作。在推测性代码区域（例如交易或关键部分）的执行期间，通常在读取集合中跟踪负载。然而，程序员或编译器可以利用显式的非事务性读取从存储器地址加载到目标寄存器中，而不将读取/加载添加到事务读取集合。同样，也提供非事务存储。这里，在推测性代码执行期间执行事务存储并且不添加到写入集合。并且商店可能立即全局可见和/或持久（即使在推测性代码区域中止之后）。换句话说，提供推测性逃避操作以“逃逸”推测性代码区域以执行非事务性存储器访问，而不会导致推测性代码区域中止或失败。

摘要： The execution of a KZBTZ finds a trailing least significant zero bit position in an first input mask and sets an output mask to have the values of the first input mask, but with all bit positions closer to the most significant bit position than the trailing least significant zero bit position in an first input mask set to zero. In some embodiments, a second input mask is used as a writemask such that bit positions of the first input mask are not considered in the trailing least significant zero bit position calculation depending upon a corresponding bit position in the second input mask.

摘要： An apparatus is described having instruction execution logic circuitry. The instruction execution logic circuitry has input vector element routing circuitry to perform the following for each of three different instructions: for each of a plurality of output vector element locations, route into an output vector element location an input vector element from one of a plurality of input vector element locations that are available to source the output vector element. The output vector element and each of the input vector element locations are one of three available bit widths for the three different instructions. The apparatus further includes masking layer circuitry coupled to the input vector element routing circuitry to mask a data structure created by the input vector routing element circuitry. The masking layer circuitry is designed to mask at three different levels of granularity that correspond to the three available bit widths.
