An absolute assembler is a computing term for an assembler which generates code which uses only absolute addresses.

There are several examples of assemblers:

GAS - the GNU Assembler

MASM - Microsoft Macro Assembler

NASM - Netwide Assembler

The assembler is the program which converts assembly code into machine code - a necessary step to prepare a program for execution.

Assembler directives are also known as pseudocode.It is instruction to assembler regarding the program to be assembled. For example ORG 4000 is an assembler directive which tells the assembler that program is stored from location 4000.

pass 1 assembler is assembler which convert assembly level language into machine level language in one pass only

1 answer


Two main options for the design of assembler are:

1. One pass assembler

2. Multi-pass assembler

One pass assemblers generally have problem of "forward referencing" which is resolved by using mulitpasses

Most of the compiler's that are used to compile programs is coded with the old assembler language. Assembler is also the older language which is used in the old Mainframe environment

The functions of an assembler mainly include fitting in parts of a computer together. This is what is commonly known as assembly of a computer.

Manual coding of 8086 is difficult hence we use a assembler or a compiler. Note that the microprocessor should be able to interpret your discussions via the program. Suppose if the instruction corresponds to word(16 bits), we use assembler directive WORD PTR, but when assembler is contacting the processor it sets a bit called 'w' indicating its a byte operation.

an assembler is aroutine program that translates assemly language source code to a machine language object code

For completing all the tasks, an assembler needs some hints from the programmer, i.e. the required storage for a particular constant or a variable, logical names of the segments, types of the different routines and modules, end of file, etc. These types of hints are given to the assembler using some predefined alphabetical strings called assembler directives, which help the assembler to correctly understand the assembly language programs to prepare the codes.

Assembler However, because the computer does not understand mnemonics, we utilise Assembler to convert them into machine language. Assembler is a machine code translator that accepts assembly code as input and outputs machine code.

An assembler takes abbreviated names for computer instructions, like "MOV", and turns them into the numeric bytes which, when loaded into memory, can be executed by the CPU.

Assembler, Compiler and Interpretor

I am not sure about the answer but think so,

Assembler: Its a program that converts a low level language into machine code, and there is a one-to-one correspondence between the source language statements and machine instructions

Macro- Assembler: It performs the same task as does the assembler but there is some times a one-to-many correspondence between the source language statements and machine instructions.

Please discuss further...

There is only one type of low-level language: assembler language. However, every architecture has its own specific version of assembler.

The task that the Assembler needs to be perform among of these are....

- the assembler takes its source code as assembly language program.
- making direct hardware access for device driver.
- produce machine code.

Single Pass Assembler A single pass assembler scans the program only once and creates the equivalent binary program. The assembler substitute all of the symbolic instruction with machine code in one pass. Advantages

Every source statement needs to be processed once.

Disadvantages

We cannot use any forward reference in our program. Forward Reference

Forward reference means; reference to an instruction which has not yet been encountered by the assembler. In order to handle forward reference, the program needs to be scanned twice. In other words a two pass assembler is needed.

The first generation C++ compiler was written in C. Newer generations of C++ compilers are written using the previous generation of C++, however some implementations also use assembler, either in part or in whole.

Bear in mind that one of the first programs ever written for a computer was an assembler. Before assembler, all code had to be written in machine code, the native language of the computer, which was labour intensive and prone to error. But that was exactly how the first generation assembler had to be written. Thereafter, the assembler was used to create the next generation assembler, and the next, until high-level languages began to appear (again, written in assembler), until C finally appeared, which eventually led to C++.
