General Description

The MC-ACT-6809 is a software compatible 6809 microprocessor implemented in VHDL using a structured and

synchronous design methodology. This flexible 8-bit microprocessor can be used for low to mid range applications

and is easily integrated into recent Actel FPGA technologies. The 6809 is designed that application specific

performance enhancements (e.g., high-speed multiplier) can be integrated, too.

Memec Design built a simulation and a hardware verification environment. The simulation environment is VHDL

based and simulates the synthesizable VHDL code of the 6809. This functional VHDL testbench reading instruction

code from a file can be used for performance check, software verification or to get used to the functionality.

A demonstration board is available which shows the functionality of the 6809 in a hardware testbench.
