Key Concepts

One-Pass Assembler

A one-pass assembler is a type of assembler that processes source code in a single pass, translating assembly language directly into machine code. It resolves symbols and generates the object program while scanning the source code only once, which requires careful design to handle forward references and optimize processing speed.

Object Diagram

An object diagram is a static snapshot that shows the instances of classes at a particular moment in time and the relationships between them. In the context of a one-pass assembler, it illustrates the objects representing various components such as symbol tables, intermediate representations, and the final object code in memory.

Interaction Diagram

An interaction diagram is used to model the dynamic behavior of a system by illustrating how objects communicate with each other over time. For a one-pass assembler, it outlines the sequence of messages exchanged between the components—like parsing modules, code generators, and memory units—during the assembly process.

Object Program

The object program refers to the machine code generated by the assembler from the assembly language source. It is the executable output that is eventually stored in memory, and its design must accommodate addressing, instruction format, and linkage required for proper execution on hardware.

Draw an object diagram and an interaction diagram for a one-pass assembler that generates the object program in memory (see Section 2.4.1).
