I've been looking at the OpenRISC architectural simulator, which includes reference to the "Custom Unit Compiler". This appears to have been a project by Marko Mlinar to generate Verilog hardware from ANSI C functions. I would be interested in knowing more, but so far all I can find is some discussion on OpenRISC forums from 5 years ago. If anyone can shed more light on this project, I'd be very interested.
