The diagram below combines Datapath A and Conditional Branch Datapath. Figure 2: Integer Computation + … A datapath is a collection of functional units such as arithmetic logic units or multipliers that perform data processing operations, registers, and buses. Along with the control unit it composes the central processing unit (CPU).
