Law, the last assembler written

Includes bibliographical references (page 24)Since instruction sets and architectures vary from one processor to the next, it is standard practice to have a unique assembler for each processor, and consequently a programmer developing software for two different target processors must be familiar with the assembler syntax for two different assemblers. An even more obvious problem occurs when software can not be transported without resolving the assembler incompatibilities. LAW eliminates the need for any other assembler by separating the processor dependent functions from the processor independent functions. A processor descriptor file (pdf) is used to describe the instruction set of the target processor and is used by LAW to generate the required object code. This project provides the user with a software tool that can be used as a baseline to generate object code for any target processor. The processor descriptor file presented in this project describes the Litton C4000 mnemonics. Block diagrams, a data flow diagram, a state diagram and LAW program listing are provided
