I would like to know detail of GPU2D feature especially Image scaling. IMX6SXRM mentioned that GPU is supporting "Programmable high quality 9-tap, 32-phase filter". But, I could not find no more information regarding image scaling.
Q1. What kind of algorithm supporting at GPU of i.MX6 SoloX?
Q2. How do I chose(programming) these algorithm before execute image scaling?

Hi Kazuma
please refer to attached Linux Guide sect.7.3.14 Video conversion
and Graphics Guide. NXP BSPs can be found on

Hi igor,
Could you please follow the above question?

Hi igor,
I appreciate your support.
I've checked your recommend documents and sample source code. (g2d_test.cpp)
But, I could not understand clearly which scaling algorithm used in GPU.
When I execute resize function via G2D API, I will set several parameters to g2d_surface structure.
then, call g2d_blit function. At this case, I suppose GPU execute resize feature automatically. Is it right?
If yes, what kind of scaling algorithm using in GPU?
Nearest-neighbor interpolation, Bilinear and bicubic algorithms, Box sampling and etc?
