That’s just moving the composition between hardware and software - the equivalence still applies. I can build any logic (software) function out of a function that evaluates NOR.
- pmiller2 6y agoFalse advertising, then, IMO.
- garmaine 6y ago...but that's exactly the claim, restated.
- pmiller2 6y agoNot really. It's completely trivial, if extremely slow (which the article acknowledges) to emulate an ALU in software, with access to a single, universal hardware gate. Why don't they just say "we put a NOR gate on a chip, then added all this other stuff (RAM, boot EEPROM, etc.) to make it function as a computer." That would, at least, be a non-misleading statement of the claim.
- magicalhippo 6y agoYes, it's a "Single board computer with 20 ICs, and a single-gate ALU". To me it's not really an ALU either, since the NOR gate doesn't really do the job I expect from an ALU.
- garmaine 6y agoThat’s how I interpreted the OP though... I really don’t know what you were reading into it.
- srott 6y agoNo, AFAIU the computation is serialized, driven by the microcode and this gate is reused for every step
