Abstract
A video image processing pipeline controller is configured to control a bandwidth at which processing functions of a video image processing pipeline communicates, over one or more memory access channels, with a system memory. The controller is configured to, based on a current frame rate at which the video image processing pipeline produces a video stream and a target frame rate of the video image processing pipeline, reduce the bandwidth while securing that the current frame rate does not drop below the target frame rate, thereby reducing a peak power consumption of the video image processing pipeline. Also a video image processing system comprising the controller is disclosed as well as a method of reducing a peak power consumption in the video image processing pipeline.
