trend of "ARM"... will this replace all other micro-controller and ...

You have all of 1 year (if that) of experience in embedded programming and you're telling the rest of us this? The ARM is fine for some things, but not for others. There is no one Magic Bullet solution in the embedded world.

I think solve all problem.

not

Surely the trend is toward ARM (low-cost, many manufacturers, good architecture) but we all leave small steps in the sand behind us (8051 and others) :)

Interesting thought. However, the one time I looked at ARM, they asked us for a $1m license fee to use it in a custom IC. Goodbye ARM! Try Renesas.com , they make the best low power high spec microcontrollers (H8 and M16); ARM is probably better if you can afford it, but my line of business would use under 50,000 units a year, so ARM is not cost effective.

WTF does all that mean?

No so.... but then I have seen some road maps :-)

Yes arm all over the place.

Arm yes... Gcc not entirely true.

Sorry I must disagree 100%, I am on a project now and the whole thing plastic enclosure, circuit board, LCD, and all componenets must cost $3 or less, and it needs a MCU, should I too use an ARM?

Crap, like everything else you post.

Not quite. The real impact of devices like the Philips LPC21xx will be on the 16 bit space.

Key parameters are pin count, and price.

Smallest ARMs are 48 pins, and in the region of $5 - both well above the average pincount/selling price of 8 bit devices.

The same process savings that move ARM down, also move smaller devices down. Right now, 80C51 are moving comfortably sub $1 in FLASH @ 8 pins, and also adding high performance Analog. (but not for the $1 :)

There is a trend for more capable cores to replace simpler cores as process improves, but the 80C51 is not exposed much to ARM at the top end, and is feeding on the simpler cores ( PIC et al) at the sub $1 point. Thus 80C51 is growing.

Learn 80C51 _and_ ARM :)

u mean "arm" is a crap?

Model T cars are totally obsolete. Flintlock rifles are totally obsolete. Steam locomotives are totally obsolete. Millions (if not billions) of 8051 processors are sold every year. You might want to look up the meaning of the word 'obsolete'.

Interesting idea - any facts or data to back up it up?

I sure wish there were small controller core modules built on the ARM that compared favorably in price to other architectures. Until there are, ARM is likely not going to make significant penetration into the industrial control marketplace. It's great for cell phones, though.

I say gcc yes.. arm not entirely true.

No, I mean your postings are.

Arm will go the way of the DoDo bird in the next couple of years. Actually, with the new smaller die sizes for the regular Intel type processors, from Intel and Via, ARM will go the way of the DoDo bird. The world will eventually switch to the Intel chips running Linux and Windows. Via's Mini-ITX and Nano-ITX and the new robotics board from Intel show the what is happening now. Everyone wants WiFi, and Bluetooth, a much bigger crop of programmers can swtich to these chips without too much trouble, plus the programming tools are a lot cheaper too. In a few years you'll need wireless internet capability for even a simple smart power switch at home. The security to keep hackers from screwing it all up will be what drives it all.

I don't think that's true either. Intel certainly doesn't think so as they also use the ARM architecture in their XP network processors.

Linux and Windows? Wrong newsgroup. :-)

ARM is also being used by Motorola in their new Dragonball series of controllers for use in PDAs, like the lastest Palms. And I believe ARM is also the CPU of choice for PDAs using Windows CE like the iPaq.

The embedded market is huge, ranging from 4-bit controller to 64-bit CPUs.

Tell that to all the mobile phone and PDA manufactuers who are still pouring squillions into their existing ARM platforms. Not surprising, given that they shipped *hundres of millions* of ARM based processors last year, and have something like 80% of the market or more. You can get Linux for the ARM too... ARM is an IP core that can be applied to all these new wizz-bang ultra small die sizes to achieve lower power and faster speeds, that is why it is so successful. It is also why virtually every major processor maker is licensed up to use ARM cores. The only place it's going in the next couple of years is up the growth curve.

On the other hand, this could be an edict from the "big guy" above, dictating "thou shalt" use ARMs everywhere.

Aha! An actual engineer amongst the opinionated students and other hoi polloi! Sadly, actual experience counts for little as you are doubtless too busy to write endless drivel here, whereas Those Who Know Without Doing have all the time in the world. Strangely.

I cannot go with this. As someone wrote "the embedded market is very deep" ... The only thing you can forecast for the future is that the future is not as projected now. Maybe in ten years Win will run on a desktop ARM in every household? Imagine the power savings...
