they are binary, but it doesn't convey the idea of reordering bits/bytes to a specific sequence. I prefer my suggestion of "reorder" because, after all, the operation (ostensibly) reorders the data.

You might also consider "invert," as in "invert the endianness," which does what "flip" tries to do with IMO a more appropriate word.

Another name for this kind of operation that has some previous history behind it is "permute". The PPC instruction set has a permute vector instruction that takes an altivec vector register (16 bytes) and re-arranges it at the byte level using the contents of another register as a list of source byte indices. Since some systems have used strange byte orderings "permute" would be a more general name than even "flip". Glenn Schrader - MITLL
