title: Tegra186 DSPK Controller
description: |
The Digital Speaker Controller (DSPK) can be viewed as a Pulse
Density Modulation (PDM) transmitter that up-samples the input to
the desired sampling rate by interpolation and then converts the
over sampled Pulse Code Modulation (PCM) input to the desired 1-bit
output via Delta Sigma Modulation (DSM).

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.
