Zilog Re-does Z80 - eZ80 Announced
Posted by Nick on 21 September 1999, 01:33 GMT
Slashdot has once again posted an article of note -- this time, Zilog, the company that created the Z80 processors that (most notably) the 82, 83, 85 and 86 run on, has decided to re-release their successful processor, calling it the eZ80. For more info, consult Zilog's page on it here. It looks like it will offer a host of improvements that could possibly lead to better calculators being developed in the future.

Hm...this is interesting, but I don't really see it appearing in calculators. The 180/182 series has comparable power and probably lower power consumption...and besides, TI seems to be leaning toward the 68000 architecture for future calcs, and it'd be really nice if they'd standardize on it (since it continues up through the 68060, an incredibly powerful chip, and has good modern support). On the other hand, they could apply their killer DSP knowledge toward developing a firebreathing RISC chip for the calcs, with onboard logic (keyboard decoding, LCD) to cut costs...ah, well.

While this new precessor may be used in calculators some time in the future, chances are that none of us will ever live to see it. TI is a smart company that is out to make money, not provide the best calculating power. The most important feature of note for this new chip is that it is (apparently) 100% compatible with z80 code. That means that there is no need to port stuff, just recompile and its all good. The other important feature is the addressing space. All the z80 asm programmers out there know what im talking about! Who wants to manually switch in 16 different rom and 8 ram pages on something like the 86. More addressing space would definatly be a plus for us lowly programmers.
Just so everyone knows, TI says "There isnt going to be a TI-86+"
