The TV80 is an 8-bit Z80-compatible microprocessor core, written in Verilog. It is based on Daniel Wallner's VHDL T80 core.


- executes 8080/Z80 instruction set
- cycle timing is similar to original Z80
- small die area
- sample peripheral with GMII interface
- Optional Wishbone wrapper for TV80 core now available


- taped out in TSMC 130nm (250 Mhz, ~20k gates)
- taped out in TSMC 65nm process (125 Mhz)
- Microprocessor-controlled verification environment
