According to the lowrisc website though, you can make a 64 bit processor if you so choose though. http://www.lowrisc.org/about/ I am sure you know this, but I just hope you understand that better possibilities exist. ;) I Wonder when they are going to crowdfund though... > l. > > _______________________________________________ > arm-netbook mailing list [email protected] > http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook > Send large attachments to [email protected] _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
