Abstract: An apparatus and method for performing a vector permute. For example, one embodiment of a processor comprises: a source vector register to store a plurality of source data elements; a destination vector register to store a plurality of destination data elements; a control vector register to store a plurality of control data elements, each control data element corresponding to one of the destination data elements and including an N bit value indicating whether a source data element is to be copied to the corresponding destination data element; vector permute logic to compare the N bit value of each control data element to an N bit portion of an immediate to determine whether to copy a source data element to the corresponding destination data element, wherein if the N bit values match, then the vector permute logic is to identify a source data element using an index value included in the control data element and to responsively copy the source data element to the corresponding destination data element in the destination vector register.

Abstract translation: 用于执行向量置换的装置和方法。 例如，处理器的一个实施例包括：源向量寄存器，用于存储多个源数据元素; 目的地向量寄存器，用于存储多个目的地数据元素; 用于存储多个控制数据元素的控制向量寄存器，与目的地数据元素之一对应的每个控制数据元素，并且包括指示源数据元素是否被复制到对应的目的地数据元素的N位值; 向量置换逻辑，以将每个控制数据元素的N位值与立即数的N位部分进行比较，以确定是否将源数据元素复制到对应的目标数据元素，其中如果N位值匹配，则向量置换 逻辑是使用包括在控制数据元素中的索引值来识别源数据元素，并且将源数据元素响应地复制到目的地向量寄存器中的相应目的地数据元素。
