One or more register sets. |

CISC |
uses complex instructions each of which may take multiple cycles. many instructions are available. many addressing modes are available. instructions have variable format. A task may be completed by a single instruction as instructions are more complex than individual instructions in RISC. programs run more slowly due to the complicated instructions/circuit. increased hardware costs. |
