hello guys, can you tell me the number of execution units in Cortex-A72 and the number of clock cycles it takes per instruction?
Thanks in advance
Hi Kallooran,
There is a block diagram in A72 TRM where you can see the execution units:
https://developer.arm.com/docs/100095/latest/functional-description/about-the-cortex-a72-processor-functions
The A72 Optimization guide gives more details:
https://developer.arm.com/docs/uan0016/latest/cortex-a72-software-optimization-guide-application-note-uan-0016a
It has a Pipeline Overview and tables of instructions latencies and throughputs.
Best regards,
Vincent.
