What is CPU (Central Processing Unit) Architecture CPU or Central Processing unit can be called the brain of the computer system because the entire processing of data is done here. It is made up of more than one microprocessors which consist of two main parts - Arithmetic and Logical Unit (ALU) and Control Unit(CU) . Arithmetic and Logical Unit The ALU performs all kinds of calculations, such as arithmetic fadd, subtract, multiply, divide, etc.), comparison (less than, greater than, or equal to), and other operations. The intermediate results of processing may be stored in the main memory, as they might be required again. When the processing completes, the final result is then transferred to the main memory. Hence, the data may move from main memory to the ALU multiple times before the processing is over. Control Unit The main function of the CU is to direct and coordinate the computer operations. It interprets the instructions (program) and initiates action to execute them. The CU...
