Two-Pass Linker

This project shows how to resolve different memory addresses. This was build specifically for a word addressable machine that has a memory of 200 words, each consisting of 4 decimal digits. The first digit is the opcode, the remaining three are the address fields.

How to compile?

javac Oslinker.java

How does it work?

This program takes in 1 argument:

1. the input file

This program deals with four different addresses:

1. An immediate operand, which the program does not change.
2. An absolute address, which the program does not change.
3. A relative address, which the program relocates.
4. A external address, which the program resolves.

Example

Use any of the address files in the given input files folder or make your own.

java Oslinker input-1.txt
