From the hardware point of view, there are a few. Most of them come from the fact that it makes instructions for sequential sub-word encodings easier to implement; for example, BCD operations are simpler, and doing string operations a whole word at a time is also easier. Re-ordering bits with a word (primarily useful for DSP) is a lot simpler. There are a few more that aren't coming to mind at the moment. It's all a trade-off. Fortunately, the advantages either way keep getting less important as transistors get cheaper and logic design tools come with native support to implement the extra complexity of an operation that's easier on the other endianness. -- Lowell Gilbert, embedded/networking software engineer http://be-well.ilk.org/~lowell/
