Hi,
While evaluating the efficiency of Cortex-M4, I found that simulator's cycle counts for several instructions are inconsistent with the manual. For example, the simulator counts 3 cycles for SMULL, while it is denoted as 1 in the Cortex-M4 technical reference manual (doc number DDI0439C, table3-1).
please someone tell me which one is correct??
I am using MDK-ARM 4.60 eval. with 'generic Cortex-M4' setting.
Thanks and regards, jay
Thanks for reply..
It seems that the simulator counts like a Cortex-M3 for several instructions, such as SMULL and SMLAL.
