Part A
What are the quality attributes of portability in embedded system design?
Answer
Portability in embedded systems refers to the ease with which software can be moved from one hardware platform to another. Key attributes include hardware abstraction, use of modular code, adherence to standard programming languages like C, and minimizing direct dependencies on specific processor architectures or peripheral registers.
What are the basic embedded systems?
Answer
Basic embedded systems are simple, low-complexity systems typically built around an 8-bit or 16-bit microcontroller. They perform a single, dedicated function, have minimal memory requirements, and often operate without a complex operating system, relying on a simple control loop or interrupt-driven architecture.
