A number of Tegra 2 based devices are about to enter the market, but do you know what the Tegra 2 is all about? Lets take a look at the technology behind the system-on-chip processor.
The Tegra 2 processor is Nvidia’s latest mobile computing processor designed to give the best of both worlds – performance and battery-life, combining processor (CPU and GPU) and power-management technologies. It delivers 4 times the performance of the previous generation of Tegra chips, approximately 10 times faster than the processors used in smartphones today.
Nvidia Tegra 250’s multi-processor architecture is the key to these stunning performance figures, and it has eight purpose-optimized, high-performance independent processors that are meant to deliver great web browsing, HD video streaming, and 3D mobile gaming. The eight processors are:
Ultra Low-Power Graphics Processor (GPU): Used for both mobile 3D gaming and 3D touch user interfaces
Video Decode Processor: Delivers full frame rate 1080p HD video playback. It also handles all three Flash video formats: H.264, Sorenson, and VP6-E.
Video Encode Processor: Runs video-encode algorithms to encode 1080p HD video for video recording and conferencing.
Image Signal Processor (ISP): Handles real-time photo enhancement features.
Audio Processor: Handles analog audio-signal processing to deliver more than 140 hours of continuous 128 kbps mp3 playback on a single battery-charge.
Dual-Core ARM Cortex A9 CPU: First dual-core for mobiles, and a general purpose CPU for web browsing and mobile computing, featuring Symmetric Multi-Processing (SMP).
ARM7 Processor: Handles system management functions and proprietary battery life extending features.
Now check out the battery-life estimates expected from an Nvidia Tegra-based tablet with 2000mAh battery and 400mW display: In standby (Display, radio off): 2000 hours; 140 hours of 128 Kbps MP3 playback; 8 hours of continuous HD video playback on LCD; 16 hours of HD video playback on external display (HDMI).
