Does SIMD width refers to number of ALUs? for example SIMD width 8 refers to there are 8 ALUs in once core?

@Kaharjan. Yes, the SIMD width refers to the number of elements than can be processed at the same time. You can think of this as having multiple ALUs that all are controlled by the same instruction. It is also correct to think of SIMD processing as having a single ALUs that is able to execution on vectors of numbers instead of single numbers. Both descriptions would be equivalent for the purposes of this class.
