Hi,

 

Yesterday I have watched a video related with kinetis introduction on freescale web page.

 

There, they said floating point multiplication is 1 cycle, and floating point division is 3 cycles (something like that, I couldn’t remember the exact values now)

 

As I know, floating point multiplication and division should be same. Aren’t they? I mean dividing a value into 4 is same operation with multiplying it with 0.25? Why are their cycles different?

 

Thanks.
