The HP Prime is a CAS-capable graphing galculator from HP announced in 2013.
It features a 3.5", 16-bit color, multi-touch, TFT screen with a 320x240px resolution.
The CAS is based on the open-source XCas engine, an powerful and advanced one, made to operate more like Maple, MATLAB, Mathematica, as opposed to something like the Nspire's CAS, which is made to be easy.
OS version history
- Pre-releases versions (from leak(s) and testers) : from rev. 3xxx to 4980
These have been found on the DVT prototype models. Production models may have different components.
Details are in the full article : HP_Prime/Hardware
- Screen: Touch Color Display 3.5" diagonal with a resolution of 320x240px
- Processor (U101): Samsung S3C2416XH-40 - ARM9 clocked at 400 MHz maximum.
- RAM Memory (U200): Hynix H5MS2562NFR - 32 MB
- Flash Memory (U201): Samsung K9F2G08U0C-SCB0 - 256 MB
- Battery: Li-Ion 3.7V, 1500 mAh (5.55Wh)
- Early / First (known) revisions (prototype):
- The calculator was named "HP Advanced Graphing Calculator"
- The back color is white
- The D-Pad was silver-colored
- DVT Prototypes:
- The calculator gets the name "HP Prime Graphing Calculator"
- The D-Pad gets black-colored
- Production models :
- The calculator gets its back color changed to Black.
About half of the RAM is taken up by the OS, the other half is free.
- Very compatible with the HP 39Gii's BASIC. (mostly additions and fixes)
- Lists are array pointers.
- Objects work through reference counters. You can have a single object reference in many places - it could be hardcoded in the main memory, or a user object on the home screen, or a variable.
- All characters are UTF16.
- Once exported, functions act like they are built in.
- The advanced grapher uses interval based math, and cannot be mixed with user functions.
No native programming capabilities are offered by default.
HP provides a free Windows software (runs correctly in Wine on other platforms) reproducing the handheld behaviour.
It is not a emulator, but a simulator (the codebase has been recompiled for Windows).
It's estimated to run between 5 and 10 times faster than the handheld depending on the application.
