A real time embedded system

• constantly senses input and provides an output
• constantly sense input and provides an output later
• Senses input at regular intervals and provides output

Name the two classifications of a real time embedded system

• hard real time system
• soft real time system
• flexible real time system

Identify the charecteristics of a Hard real time system

• Deterministic output in specified time
• Zero tolerance
• Flexible tolerance

In the design of a real time embedded system, the worst case response time of the system should be less than the deadline

• True
• False

For the above figure "click" the statements that are TRUE

• Hard real time systems has zero tolerance
• Deadline can be the time given by a manufacturer as a specification of a system
• The actual specification of a system will have a greater tolerance than the worst case time
• Average time can be greater than the worst case time
• There is lot more flexibility with the soft real time systems in terms of their response
