Researchers have used carbon nanotubes to make a general-purpose, RISC-V-compliant processor that handles 32-bit instructions and does 16-bit memory addressing. Performance is nothing to write home about, but the processor successfully executed a variation of the traditional programming demo, “Hello world!” It’s an impressive bit of work, but not all of the researchers’ solutions are likely to lead to high-performance processors.
