	  the Tegra210 has four Cortex-A57 cores paired with four Cortex-A53
	  cores in a switched configuration. It features a GPU of the Maxwell
	  architecture with support for DX11, SM4, OpenGL 4.5, OpenGL ES 3.1
	  and providing 256 CUDA cores. It supports hardware-accelerated en-
	  and decoding of various video standards including H.265, H.264 and
	  VP8 at 4K resolution and up to 60 fps.

	  Besides the multimedia features it also comes with a variety of I/O
	  controllers, such as GPIO, I2C, SPI, SDHCI, PCIe, SATA and XHCI, to
	  name only a few.
