23. RISC Vs CISC Low cycles per second, large code sizes Small code sizes, high cycles per second Register to register: "LOAD" and "STORE" are independent instructions Memory-to-memory: "LOAD" and "STORE" incorporated in instructions Single-clock, reduced instruction only Includes multi-clock complex instructions Emphasis on software Emphasis on hardware RISC CISC
