2022-10-02Major shifter-ALU redesignAlejandro Soto
The shifter unit now works in parallel with the ALU and is no longer part of it. Instructions that use the shifter as input to the ALU will now take an additional cycle, unless the control unit can detect a "trivial shift" situation where the shifter's output will be the same as its input. This change improves Fmax substantially.
