摘要
在不增加顶层进位级联超前进位加法器(TC2CLA)模块延迟时间的条件下,为最大限度地扩展操作位数,在分析混合模块TC2CLA的延迟时间公式的基础上提出了混合模块顶层级联超前进位加法器无等待时间序列.给出了混合模块TC2CLA无等待时间序列和无等待时间完全序列的定义,推证出序列的延迟时间公式及一系列重要性质.
The hybrid modules Top-level Carry Cascade Carry Lookahead Adders（TC^2CLA） without waiting time sequence was advanced on the basis of analysis delay time formula of hybrid modules TC^2CLA for purpose of the fullest expanding operand bit of TC^2CLA under conditions of not raising delay time of TC^2CLA.The definitions of hybrid modules TC^2CLA without waiting time sequence and without waiting time complete sequence were given,and the delay time formula and it′s a series of important properties were deduced.
