Features of Tegra:

The reason why NVIDIA calls Tegra a "computer on a chip" is because this chip not only contains an ARM 11 processor core, It also includes a graphics processing unit, multimedia processor, memory and peripheral devices. Just a low-power chip less than the size of a coin can independently implement many functions. Compared with Intel's x86 architecture, which started with PCs, the ARM-based Tegra is more like a development starting from mobile phone processors. It cannot run operating systems such as Windows XP on x86 PCs, but the ARM architecture lightweight operating system that has been used on mobile phones for many years can better adapt to its high-speed and low-power consumption needs.
