WebDec 18, 2014 · In bitfield cases, I strongly believe that it will pay to operate on 32 bits rather than on 8 bits, because loading a byte and storing a byte will cost exactly the same amount of clock cycles. Loading, modifying and storing a 32-bit value might give much better possibilities than loading, modifying and storing an 8-bit value.

WebWhy and when to use a bitfield¶ In most language, the smallest memory chunk that you can manipulate, that is the smallest variable size available, is a small integer, which is, on most architecture, eight bits. It is not possible to manipulate directly the individual bits, for example, setting bit number 4 to zero leaving the other bits untouched.
