Project 6: The Assembler

Objective: Develop an assembler that translates programs written in Hack assembly language into the binary code understood by the Hack hardware platform. The assembler must implement the Translation Specification described in Chapter 6, Section 2.

Resources: The only tool needed for completing this project is the programming language in which you will implement your assembler. You may also find the following two tools useful: the assembler and CPU Emulator supplied with the book. These tools allow you to experiment with a working assembler before you set out to build one yourself. In addition, the supplied assembler provides a visual line-by-line translation GUI, and allows online code comparisons with the outputs that your assembler will generate. For more information about these capabilities, refer to the Assembler Tutorial (see the Tools section in this site).

Contract: When loaded into your assembler, a Prog.asm file containing a valid Hack assembly language program should be translated into the correct Hack binary code and stored in a Prog.hack file. The output produced by your assembler must be identical to the output produced by the assembler supplied with the book.

Building Plan: We suggest building the assembler in two stages. First write a symbol-less assembler, i.e. an assembler that can only translate programs that contain no symbols. Then extend your assembler with symbol handling capabilities. The test programs that we supply for this project come in two such versions (without and with symbols), to help you test your assembler incrementally.
