Further documentation arm architecture for self-driving car type pdf available here. The Tegra APX 2500 was announced on February 12, 2008.
APX 2600 was announced in February 2009. Tegra’s power did not provide much advantage. Linux distribution was also announced on the Nvidia developer forum. Though the chip was codenamed Kal-El, it is now branded as Tegra 3. In March 2015, Nvidia announced the Tegra X1, the first SoC to have a graphics performance of 1 teraflop.
4 “Elemental” demo, running on a Tegra X1. 32KB L1 cache per core and a shared 1MB L2 cache. SoC uses a higher clocked CPU and GPU. The Tegra 2 video decoder is largely unchanged from the original Tegra and has limited support for HD formats.
The lack of support for high-profile H. 264 is particularly troublesome when using online video streaming services. While all cores are Cortex-A9s, the companion core is manufactured with a low-power silicon process. This core operates transparently to applications and is used to reduce power consumption when processing load is minimal.
