OSU8 began as a student project in 1994 to create a simple but functional 8-bit microprocessor, starting with a definition of the architecture to implementation in a Xilinx FPGA chip, and full-custom CMOS implementation. Over a period of about six months, the project came together and was, more or less, a success. The Xilinx-based hardware actually ran some code, but would crash after several dozen instructions. Gate-level simulation would run code correctly. Perhaps someday I`ll revisit the project and troubleshoot the real hardware, and maybe even fab the full-custom CMOS chip.
