This is a collection of tools and resources for soft-core systems based about a CPU like that in the MC6801 and MC6803 microcontrollers. The CPU itself is John E. Kent's cpu01.vhd file. John has been a huge inspiration in the development of this project. The assembler and linker are from Alan Baldwin's ASxxxx tools project. Alan has also has been a help. This project was first developed for the Computer Systems Lab course that I regularly teach. The materials in this project may be useful to others interested in such softcore processor design.
