The Nokia N900 is a smartphone made by Nokia. It supersedes the Nokia N810. Its default operating system, Maemo 5, is a Linux-based OS originally developed for the Nokia 770 Internet Tablet. It is the first Nokia device based upon the Texas Instruments OMAP3 microprocessor with the ARM Cortex-A8 core. Unlike the three Nokia Internet tablets preceding it, the Nokia N900 is the first Maemo device to include phone functionality (quad-band GSM and 3G UMTS/HSDPA).
The N900 functions as a mobile Internet device, and includes e-mail, web browsing and access to online services, a 5 mega pixel digital camera for still or video photography, a portable media player for music and video, calculator, games console and text processor, SMS, as well as mobile telephony using either a mobile network or VoIP via Internet (mobile or Wi-Fi).Maemo provides an X-terminal interface for interacting with the core operating system.
It was launched at Nokia World on September 2, 2009 and was released on November 11, 2009 in the United States and 9 European countries.
The Nokia N900 was launched alongside Maemo 5, giving the device an overall more touch-friendly interface than its predecessors and a customizable home screen which mixes application icons with shortcuts and widgets. Maemo 5 supports Adobe Flash Player 9.4, and includes many applications designed specifically for the mobile platform such as a new touch-friendly media player
The Nokia N900 is powered by a high-end OMAP 3430 ARM Cortex A8 which is a System-on-a-chip made by Texas Instruments based on a 65 nanometer CMOS process. The OMAP 3430 is composed of three microprocessors; the Cortex A8 running at 600 MHz (up to 1.15 GHz with good overclocking) used to run the OS and applications, the PowerVR SGX 530 GPU made by Imagination Technologies which supports OpenGL ES 2.0 and is capable of up to 14 MPolys/s and a TMS320C64x, the digital signal processors, running at 430 MHz used to run the image processing (camera), audio processing (telephony) and data transmission. The TMS320 C64x main purpose is to offload the Cortex A8 from having to process audio and video signal.Moreover the OMAP 3430 on some N900 devices has been successfully over-clocked up to 1150 MHz by using a modified kernel and editing the kernel power configuration file.The system has 256 MB of dedicated high performance RAM (Mobile DDR) paired with access to 768 MB swap space managed by the OS.This provides a total of 1 GB of virtual memory.
