DeWarp IP

The DWP300 DeWarp IP delivers real-time geometric distortion correction through a hardware/software architecture enabling precise lens dewarping in-line with the encoding pipeline.

Designed for optimal silicon area and power efficiency, the DWP300 DeWarp IP combines a customizable software driver that generates mesh configurations for a wide range of geometric transformations with a dedicated hardware core executing the transformation in real time on full video.

Architecture

Hardware Core
A dedicated hardware core that performs real-time geometric transformations on the full video stream.
Integration with a hardware encoder result in no intermediate frame buffering, minimizing memory bandwidth usage and latency.

Software Driver
Customizable driver generates mesh configurations for a wide range of distortion type customers can adapt the solution.
