0012 description: |
0013 The image renderer, or the distortion correction engine, is a drawing
0014 processor with a simple instruction system capable of referencing video
0015 capture data or data in an external memory as 2D texture data and performing
0016 texture mapping and drawing with respect to any shape that is split into
0017 triangular objects.
0018
0019 The image renderer light extended 4 (IMR-LX4) is found in R-Car Gen3 SoCs.
