# From cypherpunks-request@toad.com Sun Feb 21 14:14:43 1993 # # Does anybody have a good idea what applications this is useful for? The old CDC CYBER machines had population count in its instruction set. Perhaps some scientific-type programmers would know what they used it for. The CYBER did not have a lot of instructions -- they were pretty practical about what they put in. i.e. != VAX # My first thought is that it's a very quick way to do linear error # detection codes, since this instruction directly computes the Hamming # weight of a code word. That was always my assumption. Anyway, it's not unprecedented. strick strick@osc.versant.com
