WebPOPCNT is the assemby instruction used in __builtin_popcount. The population count (or popcount) of a specific value is the number of set bits in that value. Calculating the … WebWe add extra instructions to the ISA in an effort to get more speed. Popcount as I mentioned earlier, can be easily done in a naive way by cascading a bunch of adders on the input, at the cost of gate count (space you could use for things like more powerful general-purpose execution units) and a long critical path through those adders.
