From Core to Kit by Mike Esch How the Nios, a RISC processor on an FPGA, came to support Linux and the GNU development tools.
alas not online at http://embedded.linuxjournal.com/magazine/issue06/ Basically he boots Linux on a soft cpu ("NIOS") which is implemented on a reprogrammable logic device (Altera's). First the Altera gets configured as a NIOS (plus whatever else you want to put on there..) then the NIOS boots a Linux build. NIOS is a SPARC-like 16 or 32-bit RISC w/out a MMU that Altera sells for their chips. Of interest here because if you can't read it you can't trust it; now you can use GNUtools on a CPU you can read. Also for embedded crypto system developers in general. ---- #include <brownpowder.fffg>
