"Cortex M4 processor is extremely low power, using less than 1 MW in many cases"
Talk about low standards. Data centers run into megawatts but I expect more power efficiency from embedded processors. (Why do articles so frequently mix up milli (m) and mega (M) like this? I get that it's just capitalization but they teach this in science classes, right?)
- jrockway 8y agoIt's probably a typo. Easy to make when you've just been saying M4 a few words earlier.
- ben_w 8y agoPerhaps. Articles like this also frequently say “PC and MAC”.
- jrockway 8y agoAh yes, Media Access Control is my favorite operating system.
- dvfjsdhgfv 8y agoYou never know, maybe they meant Mandatory Access Control.

- niklasrde 8y ago1mW sounds very low though. Edit: Just had a look, depending on the implementation, "dynamic power" usage is as low as 12.26 µW/MHz [1] [1]: https://developer.arm.com/products/processors/cortex-m/cortex-m4 https://developer.arm.com/products/processors/cortex-m/corte...
