+-   Polymorphic chips have multiple 'personalities' on Thursday June 12 2008, @05:04PM Stony Stevenson

Stony Stevenson writes "US computer scientists have created a way to design polymorphic integrated circuits that can rapidly reconfigure themselves with multiple functions. Researchers at Rice University said that the "n-variant" chips can assume one identify or a subset of identities at a time depending on the user's needs. The engineers claim that building multiple "personalities" into integrated circuits can offer better security, circuit optimisation and customisation without sacrificing the related power, delay and area metrics. With 'n-variant' integrated circuits it is possible to design portable media players that are inherently unique. New methods of digital rights management can be built upon such devices. For example, media files can be made such that they only run on a certain variant and cannot be played by another."
