Cortex-M0+ a year after: smaller, thriftier and smarter!arm Blogs - Thomas Ensergueix, CPU Product Manager, ARMMay. 22, 2013 |
As usual it happened late on Friday afternoon. A couple of weeks ago a message arrived in my inbox from one of our latest ARM® Cortex™-M0+ partners: “We’re using 90LP and a similar configuration to your “min” with just a couple of additional and relatively small options and we can’t match your reported dynamic consumption (11.2µW/MHz). We can’t figure out what’s wrong, can you please help to find out what we may have missed?”
For a fraction of a second I wondered whether I should pretend I was already gone and come back to them on Monday? Well...no, I wanted to get to the bottom of it, and we start exchanging mails: How many tracks for the cell library? Target synthesis frequency? Which precise processor options? And after each exchange, I got even more confused.
