Also called an adder. A circuit in a computer that adds two binary numbers, or a unit circuit that handles one digit of a binary addition mechanism. The latter has three input terminals (A, B, C') and two output terminals (C, S). A and B each receive one digit of the operand (0 or 1), and C' receives a carry signal (0 or 1) from the lower order. That digit of the sum (0 or 1) is sent out as a signal to S, and the carry signal (0 or 1) to the higher order is sent out to C. → Related topic: Half adder Source : Heibonsha Encyclopedia About MyPedia Information |
加算器とも。コンピューターにおいて二つの二進数を加算する回路,または二進法による加算機構の1けた分を受けもつ単位回路。後者は3個の入力端子(A,B,C′)と2個の出力端子(C,S)をもち,AとBとにはそれぞれ演算数の1けた(0か1)が入り,C′には下位からのけた上げ信号(0か1)が入る。Sには和のそのけた(0か1)が,Cには上位へのけた上げ(0か1)が信号として送り出される。 →関連項目半加算器 出典 株式会社平凡社百科事典マイペディアについて 情報 |
