Embedded Processor (Microcontroller)

• Processor optimized for low cost

  • No cache
  • Small memory
  • No disks
  • 4 bit/8 bit/16 bit
  • No FP
  • No complicated datapath
  • Multicycle instruction interpretation
  • Simple/no operating system
  • Programs are static

• Low performance

  • 1 MIPS is enough if 1 ms is the time scale

• Integrate on a single chip
