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.

Software side

Features

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.[1]

Components

These have been found on the DVT prototype models[2]. Production models may have different components.

  • Screen: Multi-Touch Color Display 3.5" diagonal with a resolution of 320x240px
  • Processor (U101): Samsung S3C2416XH-40 - ARM9 (core: ARM926EJ-S) 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)

Hardware Revisions

  1. Early / First (known) revisions (prototype):
    • The calculator was named "HP Advanced Graphing Calculator"
    • The back color is white
    • The D-Pad was silver-colored
  2. DVT Prototypes:
    • The calculator gets the name "HP Prime Graphing Calculator"
    • The D-Pad gets black-colored
  3. Production models :
    • The calculator gets its back color changed to Black.

Programming

About half of the RAM (~ 16MB) is taken up by the OS, the other half is free.[1]

HP-Basic

  • Very compatible with the HP 39Gii's BASIC. (mostly additions and fixes)
  • Lists are array pointers.[1]
  • 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.[1]
  • All characters are UTF16.[1]
  • Once exported, functions act like they are built in.
  • The advanced grapher uses interval based math, and cannot be mixed with user functions.[1]

Native

No native programming capabilities are offered by default.

Emulation

HP provides a free Windows software (runs in Wine on other platforms, but with pausing and BLIT issues) reproducing the handheld behaviour.
It is not a emulator, but a simulator (the codebase has been recompiled for Windows).[3]
It's estimated to run between 5 and 10 times faster than the handheld depending on the application. [4]
