Which architecture is easier to pipeline?

• CISC

• RISC

• Both CISC and RISC

• Neither CISC nor RISC

Answer explanation

RISC architecture is easier to pipeline because it uses a smaller set of simple instructions, allowing for more efficient instruction execution and better parallelism. CISC, with its complex instructions, complicates pipelining.
