1. Differentiate between embedded systems and general computing systems, highlighting key characteristics and design constraints.

2. Explain the purpose of embedded systems in various application areas like automotive, telecommunications, and medical devices.

3. Compare and contrast different types of embedded systems based on their complexity, performance requirements, and cost considerations.

4. Discuss the fundamental quality attributes of embedded systems, such as reliability, real-time response, power efficiency, and security, and their significance in design.

5. How does the design process for embedded systems differ from that of traditional software development? Explain the importance of co-design and hardware-software interaction.

Unit 2: The Typical Embedded System:

1. Describe the core components of an embedded system, including the processor, memory, sensors and actuators, communication interfaces, and firmware.

2. Analyze the role of different types of memory (RAM, ROM, Flash) in embedded systems and discuss trade-offs in choosing the appropriate memory solution.

3. Explain the purpose and functionality of various sensors and actuators commonly used in embedded systems, and provide examples of their applications.

4. Discuss different communication interfaces (serial, I2C, SPI) used in embedded systems and their suitability for different data rates and protocols.

5. Define embedded firmware and explain its relationship with hardware components. How is firmware designed and developed for specific embedded systems?

Unit 3: Embedded Firmware Design and Development:

1. Compare and contrast various programming languages used in embedded systems development, like C, C++, assembly language, and scripting languages.

2. Explain the specific features and limitations of programming in embedded C, focusing on memory management, pointer arithmetic, and bit manipulation.

3. Discuss best practices for writing efficient and reliable embedded code, including modularity, data structures, and error handling.

4. How can debuggers, simulators, and emulators be used to effectively test and debug embedded firmware? Explain their advantages and limitations.

5. Describe the role of real-time operating systems (RTOS) in embedded systems and their impact on program development and task scheduling.

Unit 4: RTOS Based Embedded System Design:

1. Differentiate between different types of operating systems (single-tasking, multi-tasking, real-time) and explain the unique requirements of RTOS for embedded systems.

2. Define and explain the concepts of tasks, processes, threads, and scheduling algorithms in the context of RTOS based embedded systems.

3. Discuss various task communication mechanisms like inter-task messaging, pipes, and semaphores, and their role in coordinating concurrent tasks in an RTOS.

4. How does task synchronization contribute to predictable real-time behavior in embedded systems? Describe common synchronization techniques like mutexes and semaphores.

5. Explain the criteria for choosing an appropriate RTOS for a specific embedded system, considering factors like performance, resource requirements, and API compatibility.

Unit 5: Integration and Testing of Embedded Hardware and Firmware:

1. Describe the process of integrating hardware and firmware in an embedded system, including board bring-up procedures and debugging techniques.

2. Explain the role of the Integrated Development Environment (IDE) in embedded system development and its features for compiling, debugging, and managing firmware projects.

3. Discuss the types of files generated during cross-compilation for embedded systems and their significance in the development process.

4. Compare and contrast the use of disassemblers/decompilers, simulators, emulators, and target hardware debugging in the testing and optimization of embedded firmware.

5. Explain the concept of boundary scan and its applications in testing and troubleshooting embedded systems hardware and firmware issues.
