Guy Harris (talk | contribs) →GE600 series: Periscope up! As shown by the sample code linked to, it doesn't require recursion, just iteration, and, for a fixed-size item, you can unroll the loop. Clean up links and add a period to the end of a sentence. |
Guy Harris (talk | contribs) →GE-600 series: A 64-bit unrolled-loop version takes about 18 instructions when compiled with x86-64 GCC 15.2 with -Os, so (a low number of) tens, maybe, but not hundreds. Maybe it would've been worse for a 36-bit number on a GE-600, given the non-power-of-2 word size, the small number of registers, and what I suspect is an inability to do A ^ Q -> A. |

The [[GE-600 series]] and its successors had Gray-to-binary conversion; without such an instruction, [[Gray code#Converting to and from Gray code|converting from Gray code]] requires multiple steps
