Amu_Ke_Fundye ALU and Data Path The CPU can be divided into a data section and a control section. The data section , which is also called the datapath. Datapath The registers, the ALU, and the interconnecting bus are collectively referred to as the datapath. Each bit in datapath is functionally identical. The datapath is capable of performing certain operations on data items. The control section is basically the control unit , which issues control signals to the datapath . Bus : A Bus is a collection of wires or distinct lines meant to carry data, address and control information. Data Bus : it is used for transmission of data. The number of data lines corresponds to the number of bits in a word. Address Bus : it carries the address of the main memory location from where the data can be accessed. Control Bus : it is used to indicate the direction of data transfer and to coordinate the timing of ...
