Davis Logic V2: Fixed-Point Sliding Window Signal Variance Estimator (Q16.16)

Module 105 from the Davis Logic V2 project provides a zero-heap, zero-copy, compile-time windowed variance estimator for streaming telemetry data. The component, authored by Jamie Davis and last updated on 2026-05-31, uses a single-pass mathematical architecture with 64-bit integer registers to compute variance on a Q16.16 fixed-point scale.

Use Cases

• Quantifying dispersion in raw telemetry streams based on the described running accumulation system.
• Monitoring signal instability profiles in embedded execution grids based on the sliding window architecture.
• Implementing single-pass variance calculation in streaming pipelines to avoid nested processing loops.
• Optimizing power consumption in hardware loops by eliminating multi-pass operations mentioned in the performance metrics.

Strengths

• Zero runtime heap dependencies (0 bytes heap used) as stated in the computational metrics.
• Outputs are constrained by hardware-level clamping rules (+2147483647 to -2147483648) to neutralize overflow risks.
• Uses a single-pass mathematical estimation, minimizing active CPU execution cycles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 4.3 KB, indicating limited scope.
