difference between control unit and arithmetic logic unit
Answers
Answer:
Explanation:
ALU
The arithmetic logic unit (ALU), another component of the processor, performs arithmetic, comparison, and other operations. Arithmetic operations include basic calculations such as addition, subtraction, multiplication, and division. Comparison operations involve comparing one data item with another to determine whether the first item is greater than, equal to, or less than the other item. Depending on the result of the comparison, different actions may occur.
CU
The control unit is the component of the processor that directs and coordinates most of the operations in the computer. The control unit has a role much like a traffic cop: it interprets each instruction issued by a program and then initiates the appropriate action to carry out the instruction. Types of internal components that the control unit directs include the arithmetic/logic unit and buses.
Answer:
Arithmetic logic unit(ALU) performs the arithmetic and logic operation. To perform this operation , the content of the specific registers are placed in the inputs of the common ALU. The ALU perform the operation and the result is then transferred to a destination register.
A Control unit or CU is circuitry that control and directs all the operations within a CPU.. It helps the computer's logic unit, memory, and both input and output devices to know how to respond to an instruction received from a program.
