CS1008 REAL TIME SYSTEMS

AIM
To understand the basic concepts, design and integration of Real Time Systems.
OBJECTIVES
• To know about the specification and design techniques of a Real Time System.
• To understand about real time task communication and synchronization
• To have a vast knowledge of queuing models and Real Time System integration.

UNIT I BASIC REAL TIME CONCEPTS 9
Basic computer architecture – some terminology - real time design issues – example real time systems – input and output – other devices – language features.

UNIT II REAL TIME SPECIFICATION AND DESIGN TECHNIQUES 9
Natural languages – mathematical specification – flow charts – structured charts – pseudocode and programming design languages – finite state automata – data flow diagrams – petri nets – Warnier Orr notation – state charts – polled loop systems – phase / sate driven code – coroutines – interrupt – driven systems – foreground/background system – full featured real time operating systems
UNIT III INTERTASK COMMUNICATION AND SYNCHRONIZATION 9
Buffering data – mailboxes – critical regions – semaphores – deadlock – process stack management – dynamic allocation – static schemes – response time calculation – interrupt latency – time loading and its measurement – scheduling is NP complete – reducing response times and time loading – analysis of memory requirements – reducing memory loading – I/O performance
