Eh... if my goal was to implement J, I would not have "implement C" as an intermediate goal. I'd use the C code base as a reference, but instead of introducing C's compromises, I'd want to iterate on direct J implementations. (The first pass would be a "toy" and probably discarded, relying mostly on lessons learned for the next pass...) Also, the chip itself has only a rather small amount of memory on each cpu (and it's somewhere between a classic cpu and a gpu in design), so I'd expect to have to spend some amount of effort and attempts to work through the issues which arise when dealing with external memory. > The evaluation kit seems affordable; but, I am afraid, the development cost > (as usual) would be the dominant part (and some of their documents look > dated). That's true. But, also, "dated" says a lot about how our industry keeps abandoning the practical issues involved with talking to hardware. Nowadays it's difficult to even find adequate documentation on the interfaces.
