Hi all,

I need help for to convert logic in following way:

if 1st bit set in (00000000000000000000000000001) i can get 1

f 1st bit set in (00000000000000000000000000100) i can get 2

f 1st bit set in (00000000000000000100000000000) i can get 11

...........................................................................................................

f 1st bit set in (10000000000000000000000000001) i can get 31

is there any instruction for ARM cortex-r4 .

" I mean to say i just want to get the set bit position number in uint32 data ".

Please help me .

Hi,

What device do you use? Is it NXP?

I would recommend contacting ARM support.

Regards,

Daniel
