Q-13 [6] CISC vs RISC. For each characteristic, indicate by circling the corresponding letter whether they are mainly true of RISC architec- tures (R), of CISC architectures (C), of both (B), or of neither (N): Instructions require varying amounts of time to excute. R C B N Instructions excute in a uniform amount of time. RC BN Load and store incorporated in instructions. RC BN Load and store are independent instructions. RC BN Emphasis on reducing cycles/instruction. RC BN Emphasis on reducing instruction/program. RC BN
