1. Components of Microprocessor ALU Control and timing unit Registers System Bus

2. ALU(Arithmetic and logic Unit) It performs arithmetic and logical operations such as addition subtraction, and , or etc Adder 5+6 operand operator Subtractor comparator

3. Control and timing unit It controls and coordinates all the activities of the computer. It generates timing signal needed to perform various operation in the processor. It coordinates with all the peripheral devices in the computer

4. Registers Registers are the fastest memory inside the computer. It is collection of flip flops. Registers are used for storing data temporarily during the instruction execution. Types Special Purpose Registers(MAR, MDR, Accumulator, Program Counter) General Purpose Registers (A, B, C, D…

5. System Bus Set of wires or path used for data and signal transmission/ transfer Data Bus Used for transfer of data between different components of CPU. Data Bus is bidirectional Address Bus Used for transfer of address from processor to memory or I/O devices It is unidirectional The number of bits in the address bus determines the size of primary memory supported by the computer. Control bus -used for transferring control signals to and from the CPU. It may be unidirectional or bidirectional Click to add text
