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 ...... . andrew queisser wrote:> 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.
