Describe the input and output interfaces of microprocessors and microcontrollers.

Definition

Description should include
  • internal microprocessor components (e.g., registers, arithmetic logic unit [ALU], central processing unit [CPU], co-processors, processor bus, primary cache memory, clock)
  • external microprocessor components (e.g., secondary cache, main memory, external I/O bus, network interface, input devices, output devices, external memory devices, secondary storage, motherboard)
  • system on a chip (SOC) – full computer on a chip.
