3 CORE SYSTEM COMPONENTS

3.1 Tegra 250 SoC

3.1.1 Dual-Core ARM Cortex-A9 CPU

The Tegra2 CPU core incorporates a dual Cortex-A9 symmetric multi-processing ARM core

supporting dual instruction issue and out-of-order and speculative execution. The CPU supports full

cache coherency for the dual symmetric processors. The processors feature dedicated 32 KB

instruction and 32 KB data L1 caches and a shared 1 MB L2 cache.

3.1.2 Ultra-Low-Power GeForce GPU

The ultra-low-power NVIDIA GeForce Graphics Processing Unit (GPU) handles 2D graphics

rendering and 3D pixel and vertex shading. The 2D engine provides all relevant low-level 2D

composition functionality including alpha blending, stretch-bit function, video scaling, anti-aliasing

and image rotation. The 3D engine is a fully programmable 3D graphics core supporting the OpenGL

ES 2.0 rendering model. The geometry and pixel processing performance make it highly suitable for

rendering advanced user interfaces and complex gaming applications.

The GPU supports the following main features:

 OpenGL ES 2.0

 Peak triangle rate of 71 million triangles per second

 Peak fill rate (with Z-reject) of 1200 million pixels per second

 Programmable pixel shader

 Programmable vertex and lighting

 Advanced 2D and vector engine

3.1.3 Audio-Video Processor Subsystem

The Audio-Video processor (AVP) subsystem includes dedicated audio and video decode hardware

acceleration, an ARM7 processor and embedded RAM. This subsystem provides full motion

playback up to 1080p high-definition video and supports H.264, VC-1 and MPEG-4 video standards

and multiple audio standards with dedicated hardware.
