Intro What is it Quick start , J2 open processor J-core is a clean-room open source processor and SOC design using the SuperH instruction set , implemented in VHDL and available royalty and patent free under a BSD license .
The rest of this page explains how to compile and install a "bitstream" file to implement this processor in a cheap (about $50) FPGA board, then how to build Linux for that board and boot it to a shell prompt.
The steps are (roughly):
