2. What’s an Embedded System? Embedded systems = –information processing systems embedded into a larger product Two types of computing –Desktop – produced millions/year –Embedded – billions/year Non-Embedded Systems –PCs, servers, and notebooks The future of computing! – Automobiles, entertainment, communication, aviation, handheld devices, military and medical equipments.

3. Embedded Systems Devices other than desktop PCs, servers, and notebooks –Electricity running through –Perform something intelligent Hardware/software which form a component of a larger system, but are concealed from user Computers camouflaged as non-computers The future of computing! 3

4. An Example Embedded System Digital Camera Block Diagram

6. Embedded System Design Concept Concept Specification HW/SWPartitioning Hardware Components Software Components Estimation - Exploration Hardware Software Design (Synthesis, Layout, …) Design (Compilation, …) Validation and Evaluation (area, power, performance, …)

7. Components of Embedded Systems Analog Components – Sensors, Actuators, Controllers, … Digital Components – Processor, Coprocessors – Memories – Controllers, Buses – Application Specific Integrated Circuits (ASIC) Converters – A2D, D2A, … Software – Application Programs – Exception Handlers –Operating systems, compilers Hardware Software

8. Research in Embedded Systems Multidisciplinary Most of Systems topic in computer science and engineering can be related to embedded systems Major topics: –Computer Architecture for Embedded Processors : ARM, AVR, etc. –Compilers –Operating Systems (example: real time) –Design Automation (Software tools for HW/SW design) –Testing, Verification, and Validation –Software for Embedded Systems

9. Research Topics in Embedded Systems Power Management –Battery life, reliability and thermal issues, energy harvesting Coupled with sensor networks –HW/SW co-design, very limited information processing and computing –Energy management Adaptation to Applications and Environment –Reconfigurable and adaptive Systems Embedded Software Security in Embedded Systems –physical attack –Attack through network
