Future of ARM as a Micro processor

(I am not in general a technology prediction guru.. but here is a interesting another orkut driven discussion: "do we use ARM processor in Embedded Systems? We have already 8085 & 8086 processors. Then why do we go for it?"
Some answers:
power. Multiprocessor (DSP+ARM), more address space, IO, ISA, power again..
here is one set:
1) speed/MIPS.2) co-processor support3) No. of I/O s4)
the peripherals
supported by both the processors5) amount of addressable
memory6) security
options


now, my view:(note, I have been a ARM guy through out my professional life).
Have ya all heard of Intel's SOC with Pentium? if u guys been following news of intel selling off its Xscale processor family to Marvin, u guys might be aware of this.. dont yet sign off Intel from the match.. with it comes a BIG set of apps... http://www.linuxdevices.com/news/NS2460545479.html and ofcourse.. two things to keep in mind: the next gen 35nm phreus or what ever new hafnium based chips will boost intel and IBM.. all ARM IP users need to scale to that tech.. but with guarenteed lower power.. will the reign of ARM still remain?? imagine the entire power of win32 and other already huge development base coming on intel based cellphones.. it'd be fun to watch how ARM responds.. look at it this way: GB ram - with IBM-DRAM on 45nm technology today?- is going to be dirt cheap - so already is the in non-volatile memories 4GB nands and what not.. 3D cores already available.. all u need is a processor - the missing link.. u'd have windows vista on cellphones - kill 2 birds in one shot -develop for a "PC" and it works on a cell too.. the only killer will be I/O ->LCD replace with tvout(already here - not too useful on travels), and input keypad.. that would be only differentiator i think.. more of cross breeding to see... life is going to be pretty exciting once more in the technology front now.. :)

For those with short memories: remember the success factors:
1. technology/sales(read cost/performance)
2. user base (again read cost/feature set)
3. developer base (again read cost of development)

Arm Introduction doc

was in orkut today and hit this neat document on ARM intro.. recomended for those starters:

11/20/06 Hi Pankaj, not sure why - something wrong with Rapidshare. I have
uploaded it to another location as well:http://ajaydudani.googlepages.com/Programming_the_ARM_Microprocessor_for_Embedded_Systems.pdf

motoming rulz

heh heh.. forget abt mot support.. there are "not so lazy" blokes arnd http://www.motorolafans.com/MotorolaFansPHPbb/viewforum.php?f=21 and orkut has a smattering of moto ming hackers(just search for A1200)...
mebbe next post might be - I dommed my cell :(( heh heh... calvin, hobbes.. here I comeeeee...

shifting blogs...

Phew... moved most of the tech posts of old livejournal here.. hopefully will be useful for someone... sometime..wish it was easier though.... am back from Indian vacation and did post a SDP2430 bring up document here: http://www.geocities.com/crecmca98/Linux/omap2430_From_almost_scratch.pdf

Also decided to move to orkut and linkedIn.. just to meetup with like minded folks :)
