Single purpose processor
  • Single purpose processor is a Digital circuit which designed to execute exactly one program.
  • In single purpose processor no program memory is required.
  • Single purpose processor is fast.
  • Single purpose processor consume low power.
  • Single purpose processor have small memory.
  • Single purpose processor is design to execute only one program.
  • It perform particular computation task.
  • So it have faster performance.
  • Size of single purpose processor is small.
  • Power consumption is low.
  • Size is small means it have less multiplexers.
  • No program memory.
  • Coprocessor, Floating point processing and peripherals are the examples of single purpose processor.
  • The datapath contains only required components.
  • Example for single purpose processor is accelerator or peripheral.
