CAS on Casio vs HP?

Now, my HP-Prime has got CAS based on XCAS.

However, I can't find details on CAS what platform Casio is using.
Does anyone have information on this matter?

IIRC it's their own. The fx-CPs (classpads) took the FX2's CAS to a more advanced level, so you MIGHT be better off searching for info on the classpad's and possibly finding some links back to the fx2.

I do OWN an fx-cp400, but I don't care for it very much as it's VERY slow, and has limited resources ATM. I purchased it around the same time as the Prime, so I haven't used it all that much beyond MUCH preferring the Prime.

Beyond that Casio's pretty closed. They've only released an SDK for a few of their calcs, and firmware updates are slow to come or IOW they're pretty much purely focused on the educational market seemingly, and try to lock everything down on most of their offerings similar to the nspire(although there's a window on the CX right now allowing ndless operation(execution of native code) under the current firmware. (I would've purchased one of those instead of the casio but at the time the casio seemed like it might end up more hackable as the fx-cg10/20 did both end up with some community C support... while the CX at the time was shipping with an unhackable firmware...)
