TI-84 Plus CE... what now, TI? O.O
« on: November 26, 2014, 08:08:20 pm »
Ok what now? O.O http://tiplanet.org/forum/gallery/image_page.php?image_id=4114

After the TI-83 Premium CE (the French TI-84 Plus C Silver Edition), here comes that thing you see above: The TI-84 Plus CE!


According to the TI-Planet news at http://tiplanet.org/forum/viewtopic.php?p=173467#p173467 it seems that the calc feels very fast. I wonder if this could be TI's response to the complains about the slow TI-84 Plus CSE processor? A much faster CSE would definitively be nice, providing that ASM programs are cross-compatible, not locked down (the fact this calc case looks a bit like a TI-Nspire CX worries me a bit) and that the calc doesn't only come out in France.

So...the non-silver calc is faster?

That would be so nice if its faster... I wonder if we could interchange parts with the regular color calc to speed it up (assuming the parts are similar enough, that case concerns me).

My main concern is that if it's really faster than a 84+CSE, then does it mean they changed the Z80 to something else? If that's the case, this could mean that CSE ASM programs won't run. Also, the calc looks a bit like a TI-Nspire. Could this be a TI-Nspire CX running a TI-84 Plus CSE emulator with no speed throttling? If that's the case, then some stuff might run much faster, but it would be kinda a waste of power like the HP 50g was (it was basically a modded HP 48 ROM running on a Saturn emulation layer). Also, there is the possibility that if this is an ARM calc and the OS was recoded, then maybe they locked it down like with Ndless, but I doubt they would ever bother recoding the entire OS to run on ARM processors.


On the other hand, if the claim about faster speed is false and that it's actually a 15 MHz 84+CSE, then does this mean that the 83 Premium CE will be a 6 MHz TI-84 Plus C Silver Edition? That would be ridiculous.

Wow, this is... interesting. I also think the redesign looks really nice! The z80 series could use an update. I too am curious about the speed and what's inside though. Maybe a better screen or some sort of graphic processor?

Looks like they streamlined the design. The CSE has a lot of air inside because of the smaller batteries and screen compared to the monochrome SE.

The faster feel might have to do with OS optimizations. I am still hoping they're using a 50MHz eZ80 cpu though.

I am not really happy with the design, it looks quite cheap IMO. At least if that runs faster than a classic 84 or a CSE, that would a plus.

I don't like the new design, and as a few others have said, I hope it isn't locked down like the nspire.
This used to contain a signature.

I actually don't mind the redesign, although I definitively prefer the CSE one. I think they did it so that it looks closer to the TI-Nspire design and a smartphone. However, the Nspire CX design isn't very great IMHO due to not having rounded edges. Non-rounded edges on a calculator makes the calculator look like it's from the late 80's or early 90's.

I rather hope it's just a TI-84+CSE in a new case, possibly with only 2 MB of flash. It would be neat if they bumped the CPU speed up to 25 MHz---I'd have to buy one. But that would require them to use a much more accurate CPU oscillator. (The old spec for the TI-83+SE was +/-20 %, so 20 MHz + 20 % would put it over the 22 MHz speed limit some overclocked units have seen.) An eZ80 seems unlikely due to the need to license a new CPU core. I look forward to learning more about this.

I personally like the new case design. I was never a fan of the curved rows of keys.

If they used a stock eZ80 that would be fine, but yeah I guess TI wants to use their own parts to keep the cost low.

That would add an extra chip, and would cost $5 (20 MHz) to $10 (50 MHz) per CPU. It's just far too expensive. The current design has the following digital ICs:
 - A custom ASIC, containing CPU, RAM, USB, bus, glue logic, charge pump for USB host mode, and lots of miscellaneous support logic. Probably < $3.
 - Flash chip, for firmware storage. Can't be integrated into the ASIC without changing the manufacturing process, but doing so would vastly increase ASIC size, and lower yield. A 4 MB chip is about $2.
 - LCD driver, which can't be integrated into the ASIC due to the high pin count the raw LCD requires. Less than $2.
 - Battery charge controller, which could be integrated into the ASIC at the cost of several extra pins due to the high power handling requirement. Costs less than $1, especially since it's TI's own chip.
 - Back light dimmer, which has the same objection to ASIC integration. Costs less than $1.

You're suggesting that TI literally double the manufacturing cost of the calculator.

Considering PCPartPicker lists several 2+ GHz CPUs for under $50, the fact a 50 MHz CPU still costs $10 is appalling...

You don't pay for just the cpu frequency.
