Davis Logic V2: Fixed-Point Sliding Window Moving Median Filter for Embedded Systems

A 3.8 KB text file containing a C++ implementation of a fixed-point sliding window moving median filter, authored by Jamie Davis and last updated on 2026-05-31. The module is designed for deterministic, zero-heap noise suppression in bare-metal embedded targets, using a Q16.16 fixed-point format and supporting window sizes from 3 to 15 taps.

Use Cases

• Suppressing high-amplitude impulsive noise in sensor telemetry streams based on the description of the filter's purpose.
• Preserving structural signal step transitions in real-time tracking systems based on the described mathematical architecture.
• Implementing deterministic, memory-bounded signal processing on microcontrollers based on the stated zero-heap and zero-copy design.
• Benchmarking non-linear filtering performance for small window sizes based on the optimization for 3 to 15 taps.

Strengths

• Explicitly uses 0 bytes of heap memory, ensuring predictable execution for safety-critical systems.
• Optimized for a specific, small window size range of 3 to 15 taps to control current draw.
• Includes guardrails against fixed-point integer wrap-around errors for even-sized windows.
• Released under the permissive CC BY 4.0 license.

Limitations

• Description metadata is limited; actual code quality and implementation details require manual inspection after download.
• Row count is unknown, which may limit suitability assessment for benchmarking.
• The dataset is very small at 3.8 KB, indicating a limited, single-component scope.
