ARMv7A family members will have PMU on the processor. Using this PMU, we can access cycle counts. Can we relay on this using the simulator?
De-merits in using Cortex A9 for single core processor
Hi Experts,
A8 is meant for single core and A9 is for multi-core based.
Consider in case of SoC is build with single core of A9 and A8 how we could compare both in terms of some metrics/parameters like power/speed ?

code compile using -mcpu for ARM platform
When using gcc to compile c code for ARM platform, we set object platform by using:
-mcpu = xxxxxx
To what extent will that affect results of compiling ?
For example:
-mcpu = cortex-a8
and
-mcpu = cortex…

ARM Context ID Register & Process Context Switch
Hi, all
What is the content of Context ID Register of ARM Cortex A9. Is it OS that is responsible for assigning the value
of Process ID and ASID? As far as I know, it is so in Linux. Is that the same in the other OSes?
Is it essential to deal with ASID if…
