Device drivers and interrupts and service mechanism:

Programming-I/O busy-wait approach without interrupt service mechanism, ISR concept, Interrupt sources, Interrupt servicing (Handling) Mechanism, Multiple interrupts, Context and the periods for context switching, interrupt latency and deadline, Classification of processors interrupt service mechanism from Context-saving angle, Direct memory access, Device driver programming

Inter process communication and synchronization of processes, Threads and tasks:

Multiple process in an application, Multiple threads in an application, Tasks, Task states, Task and Data, Clear-cut distinction between functions. ISRS and tasks by their characteristics, concept and semaphores, Shared data, Interprocess communication, Signal function, Semaphore functions, Message Queue functions, Mailbox functions, Pipe functions, Socket functions, RPC functions.

Real-time operating systems:

OS Services, Process management, Timer functions, Event functions, Memory management, Device, file and IO subsystems management, Interrupt routines in RTOS environment and handling of interrupt source calls, Real-time operating systems, Basic design using an RTOS, RTOS task scheduling models, interrupt latency and response of the tasks as performance metrics, OS security issues. Introduction to embedded software development process and tools, Host and target machines, Linking and location software.

Course outcomes:

The students should be able to:

• Distinguish the characteristics of embedded computer systems.
• Examine the various vulnerabilities of embedded computer systems.
• Design and develop modules using RTOS.
• Implement RPC, threads and tasks

Question paper pattern:

• The question paper will have TEN questions.
• There will be TWO questions from each module.
• Each question will have questions covering all the topics under a module.
• The students will have to answer FIVE full questions, selecting ONE full question from each module.
