DC misses on register only instructions

DC misses on register only instructions

Hi, there, apology for this seemingly entry level question.

The issue: CodeAnalyst reports that some instructions have many DC misses, even though these instructions have no main memory access at all. Both operands are XMM registers. For example, "mulps %xmm0 %xmm1"

How should I interpret this?

 

Thanks ahead
