Overview

This user guide provides technical details on graphics APIs and driver support for NXP i.MX application processors, including the i.MX 6, i.MX 7, and i.MX 8 series. It specifically focuses on the G2D (2D Graphics) API, which offers a hardware-independent interface for 2D Bit blit (BLT) functions. Key features described include RGB and YUV color format conversions, alpha blending using Porter-Duff rules, high-performance memory copying, up-scaling/down-scaling, and rotation (90/180/270 degrees). The document details structures like g2d_surface and g2d_buf, provides API function descriptions for device management (open/close/blit), and outlines GPU scalability for OpenCL and OpenVX support across the i.MX product family.

Use Cases

  • Developing graphics-intensive applications for i.MX-based embedded systems.
  • Implementing hardware-accelerated 2D image processing, including scaling and rotation.
  • Configuring graphics drivers and APIs for Linux and Android environments on i.MX hardware.
  • Optimizing video performance using G2D hardware acceleration on i.MX 6, 7, and 8 series processors.
