Cross compiling node.js for microblaze

[Simon Vincent]

Will node.js work on other hardware platforms other than X86 and ARM? 

If I managed to get it to compile for microblaze would it work or would I be wasting my time?

Thanks

Simon

Just making it compile won't do you much good. V8 (the JS engine) is
a run-time code generator. You would have to teach it the MicroBlaze
instruction set and that's no easy task. For comparison, the MIPS
back-end is 34 kLoC spread across 30+ files.

Hi Simon,

I looked into a different approach of putting JS on a FPGA by writing a JS interpreter in a high-level-language to VHDL toolchain.  Sadly, the low clock speed of the FPGA makes interpreting JS painfully slow and it was impractical.  Dealing with timed logic and I/O also proved to be outside what was possible with callbacks alone.  

The good news is tiling dozens of cores seemed perfectly reasonable.

Thanks for the info. I think I will have to give node.js a pass on the microblaze. It looks far too much work!

Regards
