The Design Article "Why MIPS is just a number" by Gaurang Kavaiya on 10/03/2010 might also be of interest. The URL is goven below: http://www.eetimes.com/design/embedded/4209273/Why-MIPS-is-just-a-number

Thank you all for keeping this discussion alive. As I am aware, the architecture of the processor matters when the processor is operated with stringent power/performance/size constraints as Smith mentioned. @Patk0317: It will be helpful if you share your thoughts about argument presented in the article you are referring to, which says the processor architecture is not that important.

I disagree. As Sanjib mentioned below, assuming that the power and performance are similar would be incorrect. Infact, the major differentiator in many cases would be how much power a MCU would consume(making it more or less suitable for a given application) and also the performance. An architecture can result in lesser cycles/task and hence maximize the performance. Of course, you could abstract it all up to C, but when it comes to running applications under power/performance/size constraints, an architecture is all that makes a difference!

Thanks for the interesting topic you have brought up for the discussion. I agree that "assuming similar performance and power, then the selection criteria are the 3P's". But is that assumption correct? Is the performance more or less independent of the MCU architecture...even when the MCU is more than 75-80% loaded?

Assuming similar performance and power, then the selection criteria are the 3P's: Peripherals, Pinout, Price. As core opcodes continue to change and branch (as in this example), binary compatible operation is quietly mentioned less; The expectation is the user is insulated from that, by 'target reselect and rebuild'. aka HLL use. Floating point may become a new differentiator, but is that a Core, or a Peripheral ?

I read an article yesterday that claims the MCU architecture is not all that important if you can code in C. The peripherals that are included on the silicon are the reason to pick a particular companies MCU. What do you think? Agree? Disagree? Why?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
