Address Generation:
We have looked at the sequencing problem from the point of view of format consideration and general logic requirements. Another viewpoint is to consider the various ways in which the next address can be derived or computed.
Various address generation Techniques |
Explicit |
Implicit |
Two-field
Unconditional branch
Conditional branch |
Mapping
Addition
Residual control |
The address generation technique can be divided into two techniques: explicit & implicit.
In explicit technique, the address is explicitly available in the microinstruction.
In implicit technique, additional logic circuit is used to generate the address. |
