Question

Difference between one pass and multi pass assembler

Answer 1

Answer:

A one pass assembler passes over the source file exactly once, in the same pass collecting the labels, resolving future references and doing the actual assembly. ... The one pass assembler prepares an intermediate file, which is used as input by the two pass assembler.

Multi pass assembler means more than one pass is used by assembler. Multi pass. assembler is used to eliminate forward references in symbol definition. It creates a number of. passes that is necessary to process the definition of symbols.
