摘要： Vector single instruction multiple data (SIMD) shift and rotate instructions are provided specifying: a destination vector register comprising fields to store vector elements, a first vector register, a vector element size, and a second vector register. Vector data fields of a first element size are duplicated. Duplicate vector data fields are stored as corresponding data fields of twice the first element size. Control logic receives an element size for performing a SIMD shift or rotation operation. Through selectors corresponding to a vector element, portions are selected from the duplicated data fields, the selectors corresponding to any particular vector element select all portions similarly from the duplicated data fields for that particular vector element responsive to the first element size, but selectors corresponding to any particular vector element select at least two portions from the duplicated data fields differently for that particular vector element responsive to a second element size.
摘要翻译：提供了向量单指令多数据（SIMD）移位和旋转指令，其指定：包括用于存储向量元素的字段的目的地向量寄存器，第一向量寄存器，向量元素大小和第二向量寄存器。第一个元素大小的向量数据域被复制。重复的向量数据字段被存储为第一个元素大小的两倍的相应数据字段。控制逻辑接收用于执行SIMD换档或旋转操作的元件尺寸。通过对应于向量元素的选择器，从复制的数据字段中选择部分，对应于任何特定向量元素的选择器响应于第一元素大小从与特定向量元素的复制数据字段类似地选择所有部分，但是对应于任何特定向量元素响应于第二元素大小从该复制的数据字段中选择至少两个部分，该特定向量元素不同。

摘要： A bit or other vector may be used to identify whether an address range entered into an intermediate buffer corresponds to most recently updated data associated with the address range. A bit or other vector may also be used to identify whether an address range entered into an intermediate buffer overlaps with an address range of data that is to be loaded. A processing device may then determine whether to obtain data that is to be loaded entirely from a cache, entirely from an intermediate buffer which temporarily buffers data destined for a cache until the cache is ready to accept the data, or from both the cache and the intermediate buffer depending on the particular vector settings. Systems, devices, methods, and computer readable media are provided.
摘要翻译：可以使用位或其他向量来识别输入中间缓冲器的地址范围是否对应于与地址范围相关联的最近更新的数据。还可以使用位或其他向量来识别输入中间缓冲器的地址范围是否与要加载的数据的地址范围重叠。然后，处理设备可以完全从中间缓冲区获得要从缓存中完全加载的数据，该中间缓冲器临时缓冲目的地为高速缓存的数据，直到高速缓存准备好接受数据，或者从高速缓存和中间缓冲区取决于特定的向量设置。提供了系统，设备，方法和计算机可读介质。
