Introduction to ARM
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.
