It's processors all the way down.
There are probably tens to perhaps even hundreds of independent processors in a modern phone/computer system design. They're elements of essentially every chip in the device - especially if they provide complex/integrated functionality or communicate digitally with other chips.
- Brian_K_White 6y agoThank you for "processors all the way down"
- bartvk 6y agoIf someone would say "processor", I'd expect them to mean the CPU, meaning the Central Processor Unit. The rest, I'd call them ICs.
- loeg 6y agoYour typical harddrive has a full ARM core in it. Sure, it's an IC, but it's also reasonable to call it a processor (co-processor?).
- taneliv 6y agoOr three cores: http://spritesmods.com/?art=hddhack&page=3 http://spritesmods.com/?art=hddhack&page=3 (2013, I think). The author only considers one of them "microcontroller-ish", the other two are "quite powerful arm9-like".
- tumblewit 6y agoSo they are essentially a combination of chips rather than a combination of logical units. I always assumed these ‘chips’ are made of logical units like computer cpus 20 years ago with different logical units but that is not true. This is probably why the M1 is better than the microsoft’s ARM implementation because probably Apple is not going the processor route and instead more tightly integrating these logical units reducing latency. This is definitely more work but the it’s probably worth it when you control every bit of the pipeline which is not possible when the pipeline is made of several vendors with their SDKs like on snapdragon based windows laptop.
