VPU performance and Max frequency

[sujithkv]

Hi,

1. We are working on Android 4.2.2 on iMX6 based custom board. What is the maximum througput (pixels per seconds) of VPU  ?

There is a performance degradation with one encode, decode and rendering streams with 1920x1080 resolution (15fps). 10-15 seconds delay is coming (streaming + decoding + rendering) with external USB camera.

2. Where can we find/change the VPU maximum clock frequency settings?

Thanks in advance,

Sujith.

Maximum supported trhoughput,  is 72,576,000 pixels /s @ VPU frequency of 266 mhz

2 x  1024 x 600 x 60hz = 73,728,000
