title: iOS: How to ascertain the CPU type, e.g. A4 or A5, or instruction set architecture arm6 or arm7?
body: <p>Does Apple provide an API that gives access to this information?</p>
  
  <p>Does the ARM have an equivalent to the x86 CPUID instruction that I could use in an asm block?</p>
  
  <p>Thanks.</p>
