c++ - How do you cast unsigned short data[32] to unsigned char* very fast -


if had convert 

unsigned short data1[32]

to 

unsigned char* data2

in tight loop executed 10 million times function use best performance?
using this

reinterpret_cast<unsigned char*>(data1);

but wondering if there better way

reinterpret_cast holy grail of performance seeking coders, namely code results in 0 clock cycles.
