title: Freescale i.MX8qxp Display Controller Fetch Unit
description: |
The Fetch Unit is the interface between the AXI bus for source buffer access
and the internal pixel processing pipeline, which is 30-bit RGB plus 8-bit
Alpha.
It is used to generate foreground planes in Display Controllers and source
planes in Blit Engines, and comprises the following built-in functions to
convert a wide range of frame buffer types.

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
