.... 15 20 over an equivalent 32 bit processor [16] 17] Using 16 bit instructions reduces the energy cost of an instruction fetch by up to 50 because the size of the memory read has been halved [18] In system s with 16 bit external busses, the advantage of 16 bit instructions is further widened [19][17] Since instruction fetch consumes about a third of the processor s energy [20] 21] total energy consumption is reduced by 15 20 , which is cancelled out by the 15 20 reduction in performance, giving approximately equal energy efficiency. The available data indicates that this technique is ....
