Characteristics of CISC

What are the characteristics of CISC?

  1. A large number of instrument
  2. A large variety of addressing modes.
  3. It offers variable-length instruction formates.
  4. Instruction is larger than one-word size.
  5. Various CISC designs are set up with two special registers for the stack pointer for managing interrupts.
  6. More data types.
  7. Institution decoding logic will be complex.
  8. Instruction for special tasks used infrequently.
  9. As operations are performed in memory, there are fewer general-purpose registers.
  10. It's possible that instruction would take more than one clock cycle to complete.
