HP Prime
The HP Prime is a programmable pocket calculator from the US manufacturer Hewlett-Packard (HP).
The HP Prime was introduced in 2013 as the successor to the two models HP 39gII and the more professional HP 50g . This is hardware version A of the computer (serial number NW280AA ). HP then released hardware version C (serial number G8X92AA ) in May 2014 , hardware version C with an improved color scheme (serial number G8X92AA ) in August 2016 and hardware version D (serial number 2AP18AA ) in July 2018 . The hardware version D, which is identified as G2 , is characterized by a larger battery, a faster processor and larger main memory and flash memory .
The HP Prime is characterized by functions that are familiar from smartphones , e.g. B. a touchscreen and expandability through apps . In addition to a standard numeric mode, the calculator also includes a computer algebra system . It is possible to switch quickly between the two modes and to exchange variables between the environments.
hardware
In hardware versions A to C, an ARM core (ARM9, 32 bit) manufactured by Samsung with a clock frequency of 400 MHz is used as the processor . The internal memory is a 32 MiB DDR-SDRAM component , which is supported by a 256 MiB flash memory . The calculator measures 18.23 cm × 8.58 cm and, with a thickness of 1.39 cm and a weight of 228 grams, is considered the thinnest and most compact device equipped with a computer algebra system. It contains a 1500 mAh lithium-ion battery that can be charged via USB .
Hardware version D is equipped with a 528 MHz i.MX 6ULL processor from NXP with Cortex-A7 core. The main memory was increased to 256 MiB and the ROM was expanded to 512 MiB.
The USB interface is also used for communication with computers, e.g. B. to transfer programs or to update the firmware .
From hardware version C, the HP Prime Wireless Kit (serial number FOK65AA ) , which can be purchased separately, enables a WLAN connection. In addition, a sensor for physical measured variables can be connected via an interface, which can be accessed via an app already included. From this version, the direct connection from device to device with USB OTG and the streaming of sensor data from a maximum of 4 sensors via the HP StreamSmart 410 (serial number NW278AA ) are also supported.
The HP Prime has a 3.5-inch color touch screen with a resolution of 320 × 240 pixels, similar to a smart phone via a gesture control can be operated. The screen is a 24-bit screen that is operated in 16-bit mode. Below the screen there is an alphanumeric keyboard, which is often assigned several times via two shift keys. Further options can be controlled via menus displayed on the screen.
Input logic
The calculator supports three different input logics: the common algebraic notation , a notation similar to mathematical notation, which HP calls textbook notation , and HP's traditional reverse Polish notation (UPN).
Exam mode
The HP Prime can be switched to a special exam mode for use in exams. In this operating mode, which can only be ended after a predetermined time interval or by entering a password , certain functions, e.g. B. Computer algebra system and programmability, switched off. The activated exam mode is signaled by a pattern of glowing LEDs on the back of the computer and can therefore be checked remotely by teachers or supervisors.
Programmability
The calculator can be programmed in a new Pascal- like language ( HP PPL ). You can use it to develop your own apps.
emulator
There is an emulator of the HP Prime , which is available in the Microsoft Store , in the Google Play Store and in the App Store , each in a free and a paid version.
