MX Cross Assembler is a command-line tool for assembling machine code for the MX architecture (or theoratically any architecture). This tool takes an assembly source file and a production mapping file in TOML format and generates binary output files for data and instruction segments.
- Source Code Parsing: Reads and tokenizes the MX11 assembly source code(or any other, if you have the correct
prod.json.tab). - Instruction and Data Segmentation: Separates
.dataand.insdirectives into respective memory segments. - Code Segmenetation: Separates the code into
.insand.nmi,.irqsections for interrupt service routines. - Symbol Resolution: Handles labels and symbolic addresses.
- Binary Generation: Outputs binary files for both data and instruction segments.
- Python 3.8+
clicklibrary for the command-line interface.jsonlibrary for parsing the production mapping.
