But, when you look at building a complete embedded system, those high end processors eat you alive on external component count and manufacturing costs. That board I just spec'd cost less that $30 to manufacture, with a PIC and every thing else that I did not require, like molex connectors and such. > As you see, part cost is no problem for ARM, but you'll need more > than one component for your project however you do it. PRECISELY!; a 32 bit part can never compete with a micro if specs are tight and cost/power requirements are astringent, which most are. Certainly anything that is manufacutured in lots of 10 or more, every penny counts and cost reduction rules the decision process, never what some employee or consult "likes". They (32+) only compete when you actually need all those mips and mops, which is rare for the vast majority of uP based products. Don't believe me, just do a little research into the numbers, not the (dollar) values, of those little 8/16 bit parts. Fairchild and such won't even talk to you about anything less than 1M in qty per quarter. For large companies, those (8/16)uP are sub $1, for qty 10k or more....... Some companies sell uP for pennies, just to get the supply contract for the passives and such on really large deals. 8/16 STILL rules the world and dominates the economics of embedded. Granted 32 bit cores that run linux are very cool and preferred by most embedded folks, but, that's a very small number of design wins with big quantity (cell phones for example), compared to their mature brethren (8/16). There are millions of design wins each year, STILL, for 8/16 bit micros.... and yes, I like ARM very much, particularly in areas of low power design, relative to intel or amd. James
