is there any known 9P implementation for FPGA? or has anyone been working on
communicating with FPGAs over 9P?
similar: there was a project at the University of York ("Styx on a Chip") that developed some sort of module that could allow devices to export name spaces. Styx and 9P2000 were by that time identical.
The earliest project was demonstrated at an Embedded Systems show at Birmingham NEC.
It was one of only two rather cool things at the show (most of the show was boring UML stuff).
The other cool thing was Lars Bok's (Esmertec) OSVM: real-time garbage-collecting Smalltalk running in 64k on a micro, offering on-the-fly code updates. Superb.
