Is the neon core completely utilised in iMX7 Android

[hariprasathgopa]

Hi All,

I am trying to optimise the graphics rendering in Android version 7.1.1 running in iMX7. I am aware that the iMX7 does not have the GPU, and it is using the software rendering engine to render the Android graphics. From the log I found that it uses pixelflinger to render the Android graphics. I also see that there are some neon code to do some blend works.

Is the pixelflinger is fully optimised ?. Does it utilise the neon core efficiently ?

I am trying to offload the rendering load to the neon core from the CPU core.

Have anyone tried to optimise the pixelflinger like this ?

Hi HARIPRASATH

regarding was it fully optimised and utilise the neon core efficiently,

none software algorithms can not fully replace hardware gpu support, as

for blending, i.MX7 has more efficient hardware support using PxP engine

described in sect.13.7.3 Top-level architecture i.MX7D Reference Manual
