How does the assembly language can be executed by CPU?

Answer 1

Assembly language programs are the Low level programs. We write Assembly Language program in basically 8085 and 8086 microprocessors.

We can have several registers to do opreations with. Accumulator is one most important Register in a assembly program.

We use several instructions like..

Arithmetic:

INR - Increment Accumulator

ADD B - Add Content of Reg. B with Accumulator

SUB, etc.

Logical:

AND - Bitwise AND

Jump Instriction:

JZ label - Jump to label if ZERO flagged

JC Label - Jump on Carry

Etc..

Example:

MVI B, 06 //Load Register B with the Hex value 06

MOV A, B //Move the value in B to the Accumulator or register A

MVI C, 07 //Load the Register C with the second number 07

ADD C //Add the content of the Accumulator to the Register C

STA 8200 //Store the output at a memory location e.g. 8200

HLT //Stop the program execution

Answer 2

The processor does not differentiate between an assembly language program, a machine language program, or even a high level program. As far as the processor is concerned, it only knows machine language. All assemblers, compilers, and linkers ultimately generate machine language.

Answer 3

No, it has to be translated to machine code.

Answer 4

It has to be translated to machine code beforehand.

Answer 5

It has to be translated into machine code -- that's what Assemblers do.
