The Arm website touts the processor[he]#039[/he]s underlying architecture as “the keystone of the world[he]#039[/he]s largest compute ecosystem,” which is plausible given the number of handheld and embedded devices with Arm processors. Arm processors are prevalent in the Internet of Things (IoT), but they are also used in desktop machines, servers, and even high-performance computers, such as the Fugaku HPC. But why look at Arm machines through the lens of assembly language?
