What is assembler directive explain assembler directive with proper example?
Assembler directives supply data to the program and control the assembly process. Assembler directives enable you to do the following: Assemble code and data into specified sections. Assemble conditional blocks. Define global variables.
What are Assembly directives?
Assembler directives are directions to the assembler to take some action or change a setting. Assembler directives do not represent instructions, and are not translated into machine code. data directive tells the assembler that information that follows is program data.
What is assembler with example?
An assembler is a program that converts assembly language into machine code. It takes the basic commands and operations from assembly code and converts them into binary code that can be recognized by a specific type of processor. Assemblers are similar to compilers in that they produce executable code.
What do you mean by assembler directives in microprocessor?
An assembler directive is a statement to give direction to the assembler to perform task of the assembly process. An assembler supports directives to define data, to organise segments to control procedure, to define macros. It consists of two types of statements: instructions and directives.
What are the three main parts of a microprocessor?
For clarity, the microprocessor can be divided into three segments, arithmetic/logic unit (ALU), register unit, and control unit. Arithmetic and Logic Unit : In this area of the microprocessor, computing functions are performed on data.
What is the importance and functions of microprocessor?
A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit.
What is the purpose of RAM and ROM?
RAM is the memory available for the operating system, programs and processes to use when the computer is running. ROM is the memory that comes with your computer that is pre-written to hold the instructions for booting-up the computer. RAM requires a flow of electricity to retain data (e.g. the computer powered on).
