Re: Part II: Partitioning an Embedded System for Multicore Design

NO RATINGS
Has anyone considered AMP where the processors have different clock speeds?  My laptop has multi-processors which is great for rendering graphics and other processes.  But how fast does a processor have to run for word processing when what I'm really doing is typing.  Better to have a processor runnig very slowly (I don't type that fast.) and not executing a lot of wait instructions.  Slower clocks require less power, longer battery life, etc. as you point out.  Isn't having a fast processor asleep and a very slow processor running without a lot of wait cycles preferable to having several very fast processors running a huge number of no-op instruction waiting for me to type the next letter.

That's exactly the idea behind ARM's new big.LITTLE architecture.
