Q. How are the instructions executed and interpreted?
All computers have a Unit which performs arithmetic and logical functions. This Unit is called as Arithmetic and Logic Unit (ALU). However how will computer decide what operation is to be carried out by ALU or we can say who will interpret the operation that is to be performed by ALU?
This interpretation is carried out by Control Unit of computer. The control unit recognizes the binary form of instruction as well as interprets instruction to generate control signals. These control signals then direct ALU to carry out a particular arithmetic or logic function on data. Thus by changing control signal desired function can be performed on data. Or on the other hand the operations that require to be performed on the data can be achieved by providing a set of control signals. So for a new operation one just needs to change set of control signals.
The unit which interprets a code (a machine instruction) to produce respective control signals is called as Control Unit (CU). A program comprises a sequence of codes. Every code is, in effect, an instruction for computer. The hardware interprets each one of these instructions and then generates respective control signals such that desired operation is performed on data.
The Control Unit (CU) and Arithmetic Logic Unit (ALU) together are termed as Central Processing Unit (CPU). CPU is the most significant component of a computer's hardware.
All these arithmetic and logical Operations are carried out in CPU in some special storage areas known as registers. Size of the register is one of the significant considerations in signifying processing capabilities of CPU. Register size indicates to the amount of information which can be held in a register at a time for processing. Larger the register size the faster can be the speed of processing.
What are the factors determine the control signals? Contents of the control step counter Contents of the instruction register Contents of the condition code flag
A series of keystrokes and mouse clicks that can be abbreviated into a one keystroke or mouse click.
Instruction Length: Variable-length instructions (Intel 80x86, VAX) need multi-step fetch and decode, but permit for a much more flexible and compressed instruction set.
