SYSTEMS, APPARATUSES, AND METHODS FOR ZEROING OF BITS IN DATA ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide systems, methods and apparatuses for execution of an instruction that uses a control vector to zero out bits starting at a specific position in each data element of a source in a SIMD processing system.SOLUTION: The execution of a VPBZHI causes, on a per data element basis of a second source, a zeroing of bits higher (more significant) than a starting point in the data element. The starting point is defined by the contents of a data element in a first source. The resultant data elements are stored in a corresponding data element position of a destination.
