Hello,

 

Can anybody tell me how many core cycles does a 32 byte / 16 bytes = 16 byte division instruction take on a MKL17Z128?

 

How to optimize the compiler (both in KDS and in MCUXpresso) in order to produce the minimal set of assembly instructions for that?

 

I haven't found any specific information about that, not even in ARM Cortex M0 Plus Manual.

 

 

Best regards,
