About G2D performance with resizing and color space conversion in i.MX6DQ.

Dear All,

 

My customer measured the below performance and the result looked bad.

 

==Test Case==

VPU --> [1080p@30, YUV(NV12)] --> GPU --> [720p@30, RGBA8888] --> Frame buffer

BSP: L3.0.35_1.1.0

 

==Result==

The bottleneck was seen on GPU processing with resizing and color space conversion.

It takes about 70 msec!

 

[Questions]

Q1. Could you tell me the performance of GPU2D (theoretical or calculation value) on above case?

  (Ex, ??ms/frame)

Q2. Do you have any workaround to improve the performance?

 

Best Regards,

Keita
