  • The Tegra K1 Technical Reference Manual ("TRM") is a technical document of over 2,300 pages targeted at those working on open source, hardware design or other low level software projects that use or target the Tegra K1 processor. The TRM focuses on the logical organization and control of Tegra K1 Series devices. It provides information for those modules that interface to external devices, or those that control fundamental chip operations. The modules detailed in this document provide an overview, any necessary programming guidelines, and a register listing for that module. Internal functional units such as video and graphics hardware acceleration are controlled by NVIDIA provided software and are not documented.

    NVIDIA provides access to the Tegra K1 Technical Reference Manual to registered developers only. To become a registered developer, please sign up for our Embedded Registered Developer Program.

    If you are already a Registered Developer, you can download the TRM from our Download Center.
