术语 | look-ahead carry generator |
释义 | look-ahead carry generator 先行进位发生器 A high-speed circuit that predicts the carry of a arithmeticun it. The package of a usual high-speed look-ahead carry generator can receive four pairs of carry transference and carry generating signal and one carry input signal and can provide a group carry across the 4 bits. The generator has also the function of carry transference and carry generating output. 能预测运算器进位的一种高速电路。一种常见的高速先行进位发生器组件能接收四对进位传 送和进位生成信号以及一个进位输入信号,并提供跨越该四位的成组进位。该器件也具有进位传送和进位生成输出 功能。 |
