Introduction to Assembly LanguageSave Article. Like Article. Assembler is a program for converting instructions written in low-level assembly code into relocatable machine code and generating along information for the loader. It generates instructions by evaluating the mnemonics symbols in operation field and find the value of symbol and literals to produce machine code. Now, if assembler do all this work in one scan then it is called single pass assembler, otherwise if it does in multiple scans just click for source called multiple pass assembler. Here assembler divide these tasks in two passes: Pass Define symbols and literals and remember them in symbol table and literal table respectively. Keep track of location counter Process pseudo-operations Pass Generate object code by converting symbolic op-code into respective numeric op-code Generate data for literals and look for values of symbols Firstly, We will take a small assembly language program to understand the working in their respective passes.
