ELEMENTS OF CPU:
The CPU is a complex IC chip having millions of transistors. As mentioned earlier, a CPU has three major identifiable parts: Control Unit (CU), Arithmetic & logic Unit (ALU) and a set of Registers. The CPU chip is interfaced with other components of the computer through a system bus (printed wires on the mother board) which has three sets of wires forming Control Bus, Data Bus and Address Bus. Figure presents the components of a CPU :
CPU has a set of Registers which is used to store some data temporarily. Register lies above Cache and Main memory in memory hierarchy of the system. The registers in CPU perform two roles:
They are used to act upon logic operations on the operators. AND OR, NEG NOT TEST XOR AND INSTRUCTION Function: It acts upon the conjunction of the operators bit by bit. Syntax: A
