Atmel will never introduce an 8051 which has greater power than their AVR chips Says who? Just look at history, it's no great secret that Atmel are dragging their feet when comes to their 8051 range. Now that they have their xmega range available they can safely introduce 64k flash, 51's at 20mips. We were promised the AT89lp6440 about 3 years ago and still today there's nothing. Do yourself a favour guys, ditch the '51 and go AVR for less than £100, with compiler supporting 64bit floats. Cheers JA All you've posted here is simply one more reason to stay away from atmel, in my opinion.. I for one have used the AVR (among numerous CPU types), whilst they're not a bad chip quite frankly there's nothing really special about them either. Also, their performance is reasonably matched by a single-cycle 8051 running at the same clock frequency.. I noticed you mention the xmega; a non-backward-compatible chip that has undergone a prolonged and difficult gestation period. Yet it too doesn't quite 'beat the hell' out of the 32-bit offerings. Also, if one had issues with an 8051 core running out of steam on the extended-math ops, I would sooner suggest looking at 32-bit processor alternatives over an AVR.. Regards, Valentin Angelovski |
