The Free-RISC8 is a Verilog synthesizable model of a simple 8-bit microcontroller.
It is binary code compatible with the Microchip Technology, Inc. 16C57 microcontroller. A variety of 3rd Party
development tools exist for this architecture making this core attractive for educational
and for use in an FPGA or ASIC (several folks have successfully done this). The core comes
with a testbench and some example programs. And again, it is synthesizable. See the on-line
manual for more details.
The Free-RISC8 was written by Tom Coonan. It was donated to The Free-IP
Project in January 2000. You can visit Tom's personal web page at http://www.mindspring.com/~tcoonan
where he has other hardware and software related projects.
The current version of the Free-RISC8 core is v1.1. These are the
changes from v1.0:
