Hello,
The following table is extracted from the Cortex-R4 whitepaper:
Could someone help me to explain that question:
My concern is that Cortex-R4 can take MOV as first instruction, ADD as second instruction to a dual-issue pair in C category means that it is not limited by the data-path pipelines resource.
So, Cortex-R4 should be able to extend the A category to a version with second instruction including a additional MOV instruction.
Why cannot use ADD(Some data processing instruction) as first instruction and MOV as second instruction?
Thanks
Hi,
I'm going to move this question to the ARM Processors community as the members there will be better placed to help you.
Regards,
Ash.
