This document discusses control functions in digital systems. A control function uses a control signal similar to an "if" statement, where an action takes place if the control signal P=1, and no action occurs otherwise. The control signal P is used as an object to specify simultaneous operations, with commas separating multiple operations that occur at the same time. Control functions allow digital systems to selectively perform operations based on the state of a control signal.

3. Control Function
 In digital system, this is often done via a control
signal
 It is similar to “ if ” statement.
 If P= 1, the action take place, otherwise no.
 P use as an Object
P : R2 R1

4. Control Function

5. Simultaneous Operations
 If two or more operation occur simultaneously,
they are separated with comas.
P : R2 R1 , MAR IR
P : R5 R3 , R2 R1
