State about the Logic Micro-operations

These operations are performed on binary data stored in register. For a logic micro-operation each bit of a register is treated as a different variable.

For example, if R and R  are 8 bits registers and1 2

 R contains   10010011 and1

 R contains   010101012

 R  AND R    000100011 2

Some  of  the  general    logic  micro-operations  are  AND,  NOT  , OR or  complements. Exclusive OR, NAND, NOR.

We have four possible combinations of input of two variables. These combinations are 00, 01, 10 and 11.  Now,  for  all  these  4  input  combination  we  can  have  2   =  16  output4 combinations of the function. This implies that for two variables we could have 16 logical operations.
