Different types of ARM Classes

Two Fun Facts About ARM

1. Power Efficiency Pioneers

ARM processors are renowned for their power efficiency, which is a major reason they dominate mobile and embedded systems. The ARM architecture was designed from the ground up to minimize power consumption.

• Over 90% of smartphones worldwide run on ARM.
• This efficiency is critical for battery-powered devices and fanless systems, where heat generation must be minimized.

2. Ubiquity in Everyday Devices

ARM processors aren’t just for smartphones. They are used in:

• Smart thermostats
• Fitness trackers
• Automotive control systems
• Industrial IoT
• Even some supercomputers Thanks to its scalable and modular architecture, ARM fits across industries from consumer electronics to mission-critical systems.
