Power management: Make it as efficient as possible without affecting the use of electronic equipment
8051:
No power management: light off 6.1MA, light on 32.2MA
with power supply (in power-down mode) management: light off 0.27uA light on 26.7MA
MCU power consumption 6.1ma when running at full speed, led power consumption 26ma
Linux is more complex:
1. Hardware is more complex: more external devices are connected, and these devices also need to be powered separately, and may need to be set separately before hibernation
2. Software is more complex: a unified framework is required, and may need to be re-initialized after waking up
