Hi All, This series adds support for J721E EAIK. Below is the detailed description of the J721E SoC and the EAIK board supporting features.
J721E EdgeAI Kit (EAIK) is a low cost, small form factor board designed for TI’s J721E SoC. TI’s J721E SoC comprises of dual core A72, high performance vision accelerators, video codec accelerators, latest C71x and C66x DSP, high bandwidth real-time IPs for capture and display, GPU, dedicated safety island and security accelerators. The SoC is power optimized to provide best in class performance for perception, sensor fusion, localization, path planning tasks in robotics, industrial and automotive applications.
See J721E Technical Reference Manual (SPRUIL1B, REVISED DECEMBER 2020) for more details about J721E SoC: http://www.ti.com/lit/pdf/spruil1
