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

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 ......

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,
