But if you use an index register instead of HL you could use an offset. Now the 8080 didn't have index registers, so this may have been an issue on these.
It usually turns out that this kind of thing seems like a win for little endian, but in fact the big endian can do these operations just as fast. It just requires a little different logic. -----Original Message----- From: Alan Cox [mailto:[EMAIL PROTECTED] Sent: Thursday, August 07, 2003 4:16 AM To: [EMAIL PROTECTED] Subject: Re: big and little endian On Mer, 2003-08-06 at 18:49, Fargusson.Alan wrote: > I suspect that little endian was an accident.

Oddly enough a On Z80 little endian is a performance win at least for non deep magic programmers because you often needed to do 8bit maths ops. If HL pointed to your data then in little endian you could fiddle with the low byte without adjusting HL, and also do 8bit converts from 16bit data without extra maths.
