  • a "reduced" instruction set, consisting only of the instructions most commonly generated by compilers
  • all arithmetic and logic instructions operate only register to register using an internal register set

  • all memory access instructions are simple register load or store instructions
  • only one memory access mode built in, others handled in software
  • instructions always aligned whole words (no short or unaligned instructions)
  • significant degree of pipeline parallelism in the hardware to optimize hardware efficiency
