ISS ISP using both RSZA and RSZB, compared with RSZA alone, is able to improve the RSZ image processing speed?

The purpose of two resizers is to allow two simultaneous outputs from a single input. It is not designed to perform parallel processing. Are you facing any performance issues with ISS?

hi,Mayank Mangla,

Sorry for my late reply,now I have a question about frame rate,I am now able to get up to 18 frame data, more than 18 frame, the image is not normal, I think maybe is the camera's clock frequency is too high, if I need to reduce the clock frequency of the camera, then I need to improve IPIPE or RSZ processing speed,so I want to know how to achieve.

what is the camera resolution?

1080P,I want to the frame rate is about 23.

At this resolution, ISP can easily process at 30fps. Please check if your sensor is configured correctly.

thank you,I will try.
