RAL :: Does mirrored and desired both values are needed for prediction of register?

In reply to rajesh.deshpande:

Thanks Rajesh.
But my doubt is still same.

  1. Why two values are needed?
  2. At predict() what is need of updating desired value?
  3. What is the use case of update() method?
    Can you or anyone else, please explain in details?

Thanks in advance.
