Architecture
vSMP
• Low active standby state power consumption• On-demand maximum quad core performance• Transparent to the OS and applications
• Variable Symmetric Multiprocessing• Uses 4 Cortex A9 high-performance CPU cores• Fifth low power, low leakage Cortex A9 CPU core - Companion • On Demand Workload Distribution• Handled by NVIDIA’s Dynamic Voltage and Frequency Scaling (DVFS)
& CPU Hot-Plug management software
RESULT
How vSMP Helps ??
Total Power = Leakage Power + Dynamic Power
Fast Process = Optimized for high frequency operation, but higher leakage
Low Power Process = Operates at lower frequency with lower leakage

Operating System Transparent Implementation
Implements both hardware-based and low level software-based management
of the Companion core and the main quad CPU cores.
The decision to turn on and off the Companion and main cores is purely based on current
CPU workload levels

NVIDIA DirectTouch Architecture
Current touch solutions rely on discrete touch modules that interface between the touch panel and the application processor.

DirectTouch Architecture
NVIDIA DirectTouch improves touch responsiveness and reduces power consumption by offloading a portion of the touch processing onto the NVIDIA
Tegra 3 processor.
Benefits of NVIDIA DirectTouch Architecture
• Higher Performance: Touch controller chips are typically based on function-specific micro-controllers that have limited data processing powers. Tegra 3 are capable of operating at much higher frequencies and therefore have sufficient headroom to deliver additional processing power
• Simplified Design: The flash memory, static RAM, power regulators, and the crystal required for the touch controller are reduced or eliminated. The interface between the touch panel and NVIDIA Tegra 3 relies on an ADC chip.
• Lower Power: DirectTouch uses the Companion CPU core. The power consumption to process touch is in fact lower than that of current touch controller based solutions.
3D Gaming3D Stereo Gaming - This capability leverages NVIDIA’s award-winning NVIDIA 3D Vision® technology to automatically, and in real-time, convert OpenGL based games and apps into Stereo 3D.
Gaming Capability• Real-time physics• Real-time Dynamic Texture Generation
Quality of Graphics in originally available version of Fruit Ninja
8x higher geometry and advancedshading delivers realistic fruit images
Fuzzy shadows and low quality texture in original version of Backbreaker
Higher quality Shadows and Textures deliver more realistic game play
COMPARISON
NVIDIA PRISM Display Technology• PRISM (or Pixel Rendering Intensity and Saturation Management)• Reduces a mobile device’s backlight power• Enhancing the pixel color • Deliver the same visual quality with substantially extended battery life.
