Q4 a) What is the difference between hard and soft real time systems? Three Processes with IDs P1, P2, P3 with estimated completion tyme of 10, 5, 7 ms and priorities 1,3 and 2 respectively (0 being highest priority) enters the ready queue together. A new process P4 with estimated completion time 6ms and priority 0 enters the ready queue after 5ms of start of execution of P1. Calculate turnaround time and waiting time of each process as well as average waiting time. Assume all the process contains onlu CPT job, no I/O jobs are involved. (5) b) What is critical section? Discuss how mutual exclusion can be implemented using Mutex Semaphores. (5) Q5 a) What do you mean by hardware software co design? What is the typical embedded product design and development approach? (5) b) What is the role of a modeling language in embedded design? Design and discuss FSM model for a coin operated tea/coffee vending machine. (5) Q6 a) What do you mean by supper loop based approach? What are the advantages of assembly language based development of embedded system firmware? Which development tools are required if the development Is carried out using Higher Level Language? (5) b) What is the role of VHDL in hardware design? What are the building blocks of layouts? Explain them in details. (5) What is the role of reset circuit in Embedded System? What are the different types of reset circuits available? Explain them in detail. Discuss how the watch dog timer operates to sense, when the program execution hangs up and how it recovers the system? (10) Write short answer on any TWO: a) Unified Modeling Language (5 x 2) b) RISC Vs CISC Architecture c) Preemptive Vs Non-Preemptive Scheduling d) OrCAD as EDA Tool 2 Q8 Page Q7
