ARM core selection

Started by andrew queisser January 5, 2007
On their website  (http://www.arm.com/products/CPUs/) ARM distinguishes 
application, embedded and secure cores but the distinction between 
application and embedded cores seems somewhat arbitrary and not explained 
very well. I'm probably missing something so I'm wondering if someone could 
explain what these categories really mean. I can see how the different cores 
have different features but it's not clear how they fall into these two 
categories.

Thanks,
Andrew 


  It dont matter what they say , Use ARM , make it work for you

 rather than study it to death ,  and be happy .

 Im working  up a ARM 9 home made  PDA , HDD , USB Host ( No PDA has

 SB Host ) , 24bit 1024/768 video ,

 It will be in parallel , i will have many ARM cpus and i will go

back and forth , testing S/W til i fnd the easiest way to create

 a open , free OpSys , that will fit in 4MB SRAM , so it boots

 in 0.2 seconds .

  Some of my ARM boxes will have only a 128/64 bw LCD ( BG Micro $10)

 and softkeys around the LCD . This i use to create the low level code
.

  And the Speech computer .  It will have fast voice recog '  and
essentially

 be a super voice recorder .

    None   of   these   box's   will   program   in    the   English
language .

   If that confuses , you dont do programming ......

   ARM instruction set is far better than any Intel micro ever ......

    Big changes coming in s/w ......

All Application ARM's have MMUs to allow generic application and OS to coexist nicely, embedded ARMS have no MMUs since application and os are tightly integrated, but sometimes have a simple MPU for some protection
