Explain logic microoperation.

The bit manipulation operations such as AND, OR, X-OR etc performed on the non-numeric data stored in the register is known as logic microoperation. It can be defined in RTL by:

P: R1←R1∨R2  (OR operation is performed on R1 and R2 then the result is stored in

                        R1 )

This microoperation is only carried out if the control variable P=1.

There are 16 different logic microoperations that can be performed using two binary variables. This is given by the relation  where n=number of binary variables.
