I understand the speed and energy efficiency of the proposed design can only be reached with specially designed hardware, but couldn't some of the expected effects be achieved on existing cpu-core-hardware designs by using the lower precision requirements? Also this could be nice code golf idea: solve algorithm xyz only with a strictly limited cpu instruction set, which could be chosen to be those operations which are very quick resp. very energy efficient on a target platform...
