Abstract
Instructions and logic provide SIMD vector population count functionality. Some embodiments store in each data field of a portion of n data fields of a vector register or memory vector, at least two bits of data. In a processor, a SIMD instruction for a vector population count is executed, such that for that portion of the n data fields in the vector register or memory vector, the occurrences of binary values equal to each of a first one or more predetermined binary values, are counted and the counted occurrences are stored, in a portion of a destination register corresponding to the portion of the n data fields in the vector register or memory vector, as a first one or more counts corresponding to the first one or more predetermined binary values.
