The reason behind endianness?

Question

So, I was wondering, why some architectures use little-endian and others big-endian. I remember I read somewhere that it has to do with performance, however, I don\'t unders

Answer 1

I would assume that it once were the hardware designers of the first processors who decided which endianness would best integrate with their preferred/existing/planned micro-architecture for the chips they were developing from scratch.

Once established, and for compatibility reasons, the endianness was more or less carried on to later generations of hardware; which would support the 'legacy' argument for why still both kinds exist today.
