Working Ternary ALU (2019)
- pandaman 3y agoThere had been working ternary computers made in the USSR[1] 60 years ago, though, as far as I know, they still had binary memory (2 ferrite bits were used to store each "trit") and that was quite a waste. 1. https://en.wikipedia.org/wiki/Setun https://en.wikipedia.org/wiki/Setun
- dvwobuq 3y agoReally cool article and I definitely appreciated the section at the end that compared ternary to CMOS. But in order to use ternary in a real processor, as suggested by the article, we would need a much more formal definition of the voltage levels of the gate. Something like this: https://www.egr.msu.edu/classes/ece410/mason/files/Ch7.pdf https://www.egr.msu.edu/classes/ece410/mason/files/Ch7.pdf Without that it’s not clear how one could do timing analysis or do dynamic gate resizing to deal with practical issues like fanout. Also, without the more formal definition it’s not even clear, to me anyway, what figures like 22 are even measuring.
