title: Freescale i.MX8qxp Display Controller Store Unit

description: |
  The Store unit is the interface between the internal pixel processing
  pipeline, which is 30-bit RGB plus 8-bit Alpha, and the AXI bus for
  destination buffer access. It is used for the destination of Blit Engines.
  It comprises a set of built-in functions to generate a wide range of buffer
  formats. Note, that these are exactly inverse to corresponding functions in
  the Fetch Unit.

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

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.
