Note that the data type sizes don’t need to match, so it’s no problem to have a union with, for example, a 32-bit and a single 8-bit integer, the 8-bit value is simply truncated if needed.

The result is a 16-bit microprocessor comprising more than 14,000 complementary metal–oxide–semiconductor CNFETs that runs standard 32-bit instructions on 16-bit data and addresses, ... They also ...
