A vector reduction instruction with non-unit strided access pattern is received and executed by the execution circuitry of a processor.Bitwise AND reduction to scalar. Bitwise AND horizontally across all lanes of a vector, and place the result in the SIMD&FP scalar destination register. Reduce the fetch and decode bandwidth Vector instructions access memory with known pattern Single vector instruction implies lots of work. Each vector instruction can perform the same type of operations on Note that compilers can vectorize code with dependences when reduction idioms can be
