ARM: Points to be noted
The story of ARM began in 1993 with a joint venture of Apple with ARM (then Acorn RISC Machines) to launch the "Apple Newton" handheld PC. And the story continues today with news that Apple is going to switch their MACs to ARM processors. What has not changed in the story is ARM's reputation as a power-efficient processor. This is the primary reason why it is so popular in smarthphones, and why it has made its way into smart cars, drones and other internet-of-things devices where it is crucial to preserve battery life and minimize heat generation. Today even data centers can run on ARM. Due to such widespread market disruption happening, I thought about putting some specific points which I think are good-to-know for users and software developers who have just begun using the ARM ecosystem ... The reason why ARM power consumption is less has to do with the inherent nature of RISC architecture on which ARM is based. RISC instructions are so simple that each of them req...
