Implementation of the FORTH programming language

FORTH is a great language for hardware bring-up, and boot firmware. It is compact, undemanding of the platform (all it needs is some memory and a serial port), and powerful.

Goals

• Support multiple CPUs
• Support multiple platforms

Implementation

• Classic, "threaded code", IP is a pointer to a pointer to machine code
• Most words defined in the FIG FORTH standard
• Omitted
  • Double-size operations
  • Vocabularies

Components

• src/i386: Source for i386 CPU (32-bit)
• src/i386-linux: Source for i386 CPU (32-bit) on Linux platform (i.e. I/O)
• src/linux: Source for Linux platform (i.e. I/O)
• src/shared: Source code common to all CPUs and platforms
• src/x86_64: Source for x86_64 CPU (64-bit)
• src/x86_64-linux: Source for x86_64 CPU (64-bit) on Linux platform (i.e. I/O)
• bld/i386-linux: Build files for i386 on Linux platform
• bld/linux: Build files for all CPUs on Linux platforms
• bld/x86_64-linux: Build files for x86_64 CPU on Linux platform
• test/x86_64-linux: Test files for x86_64 CPU on Linux platform

How to build

1. cd to appropriate build directory, based on CPU and platform, eg. bld/x86_64-linux
2. make all
