TV80

## Description

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

## Features

\- 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

## Status

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