A combination NAND and flip-flop circuit includes a pre-NAND scan circuit operable to receive a plurality of input signals and produce first and second output signals for receipt by a NAND gate. The plurality of signals comprises signals indicative of a first data signal, a second data signal...
记忆单元中的大部分能够被封装到flip-flop(触发器)中,它是一种底层时序门(sequential gate),也是具有记忆功能的最小记忆单元。其能够储存一个基本的比特位,我们称之为“寄存器(register)”(和后面CPU内部的寄存器不是一个东西)。 背景知识 时钟(Clock) 主时钟(master clock)提供连续的交变信号序列,硬件实现基于振...
