Submission + - Project IceStorm passes another milestone: building a CPU (excamera.com) 2
Project IceStorm http://www.clifford.at/icestor... aims to change that by reverse-engineering some Lattice FPGAs to produce an open-source toolchain, and today it passed a milestone. The J1 open-source CPU is building under IceStorm, and running on real hardware. The result is a fairly puny microcontroller, but possibly the world's most open one.
