hi
well now the first step is done
the initial schematics are now complete
http://www.whipy.demon.co.uk/geep-sch.pdf
and the coresponding pcb artwork
http://www.whipy.demon.co.uk/geep.pdf
we now would like some to look it over and let us know if there are
any potential problems before we commit to having the prototype pcbs
made
the geep is a open source GNU GPL licenced unit
it offers
ep9302 200Mhz arm cpu
up to 256MB of sdram
512MB of on board flash
T10/100 ethernet
2 * usb
rs232
ps/2
ac97 audio codec
ide
compact flash
2 * 100khz to 25Mhz DSS frequency genorators
a spartan 3 xc3s400 fpga (75% avalable for user ip)
64MB ddr video ram
dvi-i video (both digital and analog)
composite video output
a 32 dio fpga port / expansion bus ( allowing for 50Mhz + signal
clocking )
a lower speed dio and analog expansion port
on a 160mm * 100mm 4 layer pcb
if verification of the design goes ok then the prototypes should be
under construction in the next 3 months , and allowing another 2 to
3 months for the software port and ip core writing before the design
is totaly finalised
anyone interested in getting involved in the development ether email
me at the email on the schematics , or in irc chat on freenode.net

(sorry that this is slightly off topic)
