parallel adder
A digital circuit that adds multiple bits simultaneously; used in computer arithmetic units.
A parallel adder is a circuit that adds multiple bits simultaneously.
A serial adder processes bits one at a time, while a parallel adder handles all bits at once, making it faster but requiring more hardware.
Compound of 並列 (parallel) + 加算器 (adder). The term is a direct calque from English 'parallel adder'.
