Embedded System

Concept

• Constraints - SWaP-C (size, weight, power, cost)
• Computation
• Shifting to IoT, FCC unlicensed 2.4GHz spectrum, also brings more points of failure and security issues.
• Microcontroller (SoC) = microprocessor + stuff on single chip
  • RAM
  • Flash/ROM
  • Devices (connects to Cyber-Physical System)
    • GPIO
    • Timing I/O - PWM, stepper-motor
    • A/D and D/A

• Keeping a system as FSM is great, but the real world is a Markov Chain.
• OS vs no-OS (a big while True loop)
