Davis Logic V2: Fixed-Point Sliding Window Linear Detrending Filter (Q16.16)

A 4.2 KB text file authored by Jamie Davis, last updated on 2026-05-31, details a bare-metal embedded signal processing module. The module implements a zero-heap, zero-copy sliding window linear detrending filter designed for real-time baseline wander cancellation in AC telemetry streams. It uses a single-pass regression solver and Q16.16 fixed-point arithmetic to subtract low-frequency disturbances like sensor drift.

Use Cases

• Implementing baseline wander cancellation for biomedical or industrial sensor data based on the described linear detrending algorithm.
• Benchmarking low-memory signal filtering techniques for embedded AI based on the zero-heap, static parameter architecture.
• Studying fixed-point arithmetic implementations for real-time ML inference based on the Q16.16 fractional layout.
• Developing educational material for digital signal processing in bare-metal environments based on the provided mathematical architecture.

Strengths

• The implementation uses 0 bytes of heap memory, as stated in the description.
• Outputs are constrained by hardware-level clamping rules to prevent overflow, as described.
• The module is licensed under Creative Commons Attribution 4.0 International (CC BY 4.0).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
