关于硬件中常见的基本存储元件的定义、中英文对应的名字会模糊,今天特地查明具体定义。
flip-flop:触发器,是时钟边沿触发,可存储1 bit data,是register的基本组成单位,结构图如下:
register:寄存器,a hardware register stores bits of information in such a way that systems can write to or read out all the bits simultaneously.就是时钟边沿触发的存储结构,是由多个flip-flop组成,可以构成register file, SRAM等,结构如下:
latch:锁存器,是由电平触发,结构图如下:
