Computer Energy Consumption

(Master of Information Science) Lecture on IoT and Edge Computing

• Computer Processing Speed

  • Number of instructions × Time per instruction
  • Proportional to Cycle count × Clock time
    • Cycle count ∝ Computational complexity?
    • Clock time = Time between signals of the synchronization signal of the CPU

• Computer Energy Consumption

  • Power × Cycle count × Clock time
    • Power ∝ Circuit size of the computer
