Hyperlexia is so much more common among those on the autism spectrum that it is starting to be thought of as primarily an autistic co-morbidity (or superpower, depending on which researcher you're reading). I don't know a very large number of aspies or HFAs, but half of those that I do know taught themselves to read before kindergarten, with no help from parents or preschool. There is only one instance mentioned in the literature of a non-autistic hyperlexic, who seemed so out of the ordinary that they did a case study just to document that a non-autistic hyperlexic could exist.
But many aspies are not hyperlexic, so the two aren't synonymous.
THere are many sources that specifically define hyperlexia to be associated only with those on the autistic spectrum, mainly AHA.
There are two types of precocious readers: "early readers"; and those with hyperlexia.
People who 'appear' to be hyperlexic but display little or no autistic, or AS, characteristics are said to be early readers.
