title: Renesas JPEG Processing Unit
maintainers:
- Mikhail Ulyanov <mikhail.ulyanov@cogentembedded.com>
description:
The JPEG processing unit (JPU) incorporates the JPEG codec with an encoding
and decoding function conforming to the JPEG baseline process, so that the
JPU can encode image data and decode JPEG data quickly.

Annotation
- Immediate include surface: `dt-bindings/clock/r8a7790-cpg-mssr.h`, `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/power/r8a7790-sysc.h`.
- 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.
