ARM: Introduction to ARM: ARM Architecture

by David Thomas on

ARM Architecture

  • Programming in ARM is like having a ‘big’ 6502.
    • Many familiar instructions.
    • ARM is a RISC chip: Reduced Instruction Set Computing.
  • There are currently seven distinct versions of the architecture.
    • Each builds upon the previous version.
    • Architecture numbers aren’t model numbers.
    • e.g. an ARM9 chip might be ARMv4 or ARMv5.
