What's the cortex-A7 pipeline's in-order and cortex-A15 pipeline's out-of-order mean?

What's the cortex-A7 pipeline's in-order and cortex-A15 pipeline's out-of-order mean? In ARM's white paper(about the cortex-A7 and cortex-A15) says as follow: I want ask the in-order and out-of-order...

Barriers in in-order cores like cortex-A53, A7

Hi experts! As you know, power efficient arm like cortexA7, A53 has in-order pipleline. However as far as I understanding, Barriers like dmb, dsb, isb are related with out-of-order memory access. But...

Interrupt on Out-of-Order pipeline of Cortex-A15

Hi, I would like to know the interrupt behavior on Out-of-Order pipeline on Cortex-A15. When some instruction is executing on Out-of-Order pipeline, one interrupt is happens. In this case, its interrupt...
