Davis Logic V2 Module 108: Fixed-Point First-Order Lag Compensator Filter (Q16.16)

Module 108 from the Davis Logic V2 project provides a zero-heap, real-time first-order lag/lead compensator filter designed for deterministic control loop stabilization in bare-metal embedded targets. The module, authored by Jamie Davis and licensed under CC BY 4.0, uses a recursive digital infrastructure with Q16.16 fixed-point arithmetic to optimize transient responses and modify phase margins. The text file, last updated on 2026-05-31, is 3.8 KB in size.

Use Cases

• Implementing deterministic phase margin adjustment in control loops based on the described lead/lag compensation architecture.
• Developing zero-heap, real-time signal processing routines for microcontrollers based on the bounded memory and branchless arithmetic design.
• Studying fixed-point (Q16.16) implementations of recursive digital filters based on the provided difference equation and scaling operations.
• Benchmarking low-power computational performance for filter algorithms based on the described dynamic power reduction techniques.

Strengths

• Explicitly uses 0 bytes of heap memory, bounded completely inside physical registers.
• Employs rigid 32-bit hardware-level saturation boundaries to eliminate integer wrap-around errors.
• File size is precisely 3.8 KB, indicating a compact, focused implementation.

Limitations

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