Module 3 - Introduction to Embedded Systems

In the context of a Data Flow Graph (DFG), what does an inward arrow represent?

• Output data

• Input data

• Process execution

• Data storage

What does the Control Data Flow Graph (CDFG) model represent?

• Only data operations

• Both data operations and control operations

• Only control operations

• Only sequential program execution

Which of the following is NOT present in a Data Flow Graph (DFG)?

• Data flow nodes

• Operations or processes

• Decision nodes

• Arrows representing the movement of data

In the context of the State Machine Model, what is an "Action"?

• A system state

• A transition between states

• A condition for triggering events

• An activity performed by the state machine

What defines a Finite State Machine (FSM)?

• It has an infinite number of states

• The number of states is finite

• It only accepts input from external sources

• It does not involve transitions between states

In a Flow Chart, which of the following symbols is typically used to represent a decision or conditional?
