Characteristics of RISC & CISC

  1. Characteristic of RISC –
  2. Simpler instruction, hence simple instruction decoding.
  3. Instruction come under size of one word.
  4. Instruction take single clock cycle to get executed.
  5. More number of general purpose register.
  6. Simple Addressing Modes.
  7. Less Data types.
  8. Pipeling can be achieved.
  1. Characteristic of CISC –
  2. Complex instruction, hence complex instruction decoding.
  3. Instruction are larger than one word size.
  4. Instruction may take more than single clock cycle to get executed.
  5. Less number of general purpose register as operation get performed in memory itself.
  6. Complex Addressing Modes.
  7. More Data types.
