Nvidia Tegra 2 也宣称出来了很久了，市面上还是鲜有基于这个处理器的产品，更不要说模块了。Nvidia对于Tegra T2也是寄予厚望，高调宣传。但是，市场上总是感觉未知庐山真面目。如今，Toradex Colibri Nvidia Tegra T2计算机模块的诞生总算是揭开了一小块面纱。
一 首先看Tegra 2 处理器。
_ NVIDIA Tegra 2 dual-core Cortex-A9 MPcore
_ Both CPUs have 32KB Instruction and 32KB Data Level 1 caches
_ 1MB shard Level 2 cache
_ VFPv3 Floating Point Unit
这里最大的特点是双1G Cortex A9 内核，对于密集计算应用一定是有优势的；另一个亮点是1MB的L2缓存，这对于视频编解码有着至关重要的作用；Cortex-A9 FPU提供高性能的单精度和双精度浮点指令，浮点运算单元对于例如傅里叶变换甚至Mp3编解码都有帮助。
二 接口的亮点。
得益于新内核内部总线的变化，先进总线接口单元（Advanced Bus Interface Unit）引入，充分匹配处理器在高主频应用下的性能和数据吞吐能力，使Tegra 2显示分辨率较以往的ARM处理器有了大幅度提高。并且提供了独立的HDMI接口，剑指消费媒体应用。
_ LCD RGB (1680 x 1050)
_ HDMI 1.3 1080p (1920×1080)
_ Analog Video (1600×1200)
摄像头的接口数据率大幅度提高，
_ CMOS/CCD Image Sensor Interface (12MP)
通用接口 支持的更加完善
_ USB 2.0 high speed Hosts/Device
_ 10/100 Mbit Ethernet
_ 16/32-Bit Data Bus
_ Touch Screen (4/5 wire)
_ Audio I/O (16 Bit stereo)
_ I2C, 4x SPI , 5x UART, 2x SDCard up to 8Bit (SDIO, MMC), One-Wire
_ Up to 110 GPIOs
视频处理更加强大，看看H.264和WMV9的解码，完全支持全高清的播放。
HD Video Decode
_ H.264
o Baseline Profile (B frames) — 1080p/20Mbps
o Main Profile (B Frames, CAVLC) — 1080p
o Main Profile (B Frames, CABAC, no weighted prediction) — 720p/6Mbps
o High Profile (B Frames, CABAC, no weighted prediction) — TDB
_ WMV9 VC-1 (Simple, Main and Advanced Profiles) — 1080p/20Mbps
_ MPEG-4 (Simple, B frames and ASP Profiles) — 1080p/8Mbps
_ H.263 (Profile 0) — 720×576/4Mbps
_ DiVX (DiVX 4/5) — 1080p/8Mbps
_ XviD (XviD Home Theater) — 1080p/8Mbps
_ MPEG-2 (Main Profile @ Main Level) — 720×576/10Mbps
_ VP6 (simple and advanced profile) — 720p30/2Mbps
_ Sorenson (simple and advanced profile) — 720×576/4Mbps
_ JPEG up to 80 Mpixel per second
编码能力相当强悍。
