TMS320F28379S: Counting leading zeros

Beat Arnet

Part Number: TMS320F28379S

Hi Support Team -

What is the most efficient way of counting the leading zeros of a 32-bit integer? I am looking for something similar to the ARM CLZ instruction for C-callable assembly.

Beat,

The CSB assembly instruction counts the number of leading 0's or 1's in the accumulator. Could you take a look at the description on p.184 of the C28x instruction set guide so see if this could work for you?
