4 Heart is having a natural pulse generator which is responsible to rythmically beating of heart. Malfunctioning of that leads to anythmic heart beating. Design a pacemaker (pulse generator) which generates electrical pulse to trigger heart, if it senses irregular(or low) heart rate. This pacemaker is typically inplanted inside body near chest. Assume appropriate design challenge and design an embeded system (pacemaker) which can sense and trigger (if required) heart to bring heart back to normal rythmic beating. For this design develop
a) Functional model/FSM which describe functioning of system
b) Hardware block diagram which describes typical hardware building bolcks
c) Software architecture which describe typical functions/drivers/tasks required in program d. Piscuss special design challenges for this design and suggest solutions/ approach
d) Suggest list of components with justification.
5 marks

5(a) What is Real time operating system's role, function in an embeded system? Describe various uCOS-II c-function which are used to implements RTOS function/role.
5 marks

5(b) What is shared data? How it is handled in RTOS? What are priority inversion problems? How priority inversion problem can be addressed/solved?
5 marks 205 206
