RISC (Reduced Instruction Set Computing) and CISC (Complex Instruction Set Computing) are two computer architectures that are predominantly used nowadays. 1 Quantitative Analyses of Program Execution • 10. Since RISC architecture allows for simpler hardware, more elements can be packed on the chip and this increases speed. A complex instruction set computer (CISC / ˈ s ɪ s k /) is a computer in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions. 15 RISC and CISC are no longer the black-and-white distinction they might have been once. 30%] where P = time to execute I = number of instructions executed C = clock cycles per instruction S = clock speed. CISC traditionally doesnt, RISC traditionally does. RISC vs CISC. (PPRC) F453 COMPUTER SCIENCE 3. In contrast to RISC, CISC chips have a large amount of different and complex instruction.
