What is the difference between ARM architecture and the typical architecture in CPUs, and why is it so revolutionary?
In: Engineering
I don‘t quite understand the question. ARM is a fairly typical architecture and it’s certainly not revolutionary. What makes current ARM architecture particularly suitable for building high-performance CPUs is that ARM instructions are carefully designed to be easier to work with in hardware. This means it can be easier (and more energy-efficient) to build an ARM CPU that executes a lot of instructions simultaneously. Also, ARM instructions tend to pack commonly occurring functionality together, which again improves their efficiency.
