title: Freescale i.MX8qxp Display Controller Pixel Engine

description:
  All Processing Units that operate in the AXI bus clock domain. Pixel
  pipelines have the ability to stall when a destination is busy. Implements
  all communication to memory resources and most of the image processing
  functions. Interconnection of Processing Units is re-configurable.
