Hello,

I don't understand following sequence of PC values after branch.

Why PC get branch address only after execution next after B instruction?

    First you need to understand the term CPU pipeline.  I recommend you perform an internet search on that term, and read some of the articles that come up.

    In the case of a C6000 CPU, a branch takes 5 cycles to work through the pipeline and finally execute.

    Thanks and regards,
