Block diagram in electronics consists of a connection of smaller standard circuits, which in turn consists of the special arrangement of components performing a circuit task. As per the below block diagram, the input buffer is a location that holds all incoming information before it continues to the CPU for processing. Input buffers can also be used to describe other hardware or software buffers used to store information before it is processed. As per the input buffer block diagram, the data is passed from the FIFO and RAB managers. Instead of creating an input buffer block diagram from scratch, use EdrawMax pre-defined templates as it provides the right facts and figures that ease the entire process.
