Davis Logic V2: Fixed-Point First-Order Allpass Phase Shifter Filter (Q16.16)

Module 106 from the Davis Logic V2 project provides a zero-heap, real-time First-Order Allpass Phase Shifter Filter for deterministic telemetry processing in bare-metal embedded systems. The module, authored by Jamie Davis and licensed under CC BY 4.0, uses a Q16.16 fixed-point format and a recursive difference equation to modify signal phase without affecting magnitude. The dataset, last updated on 2026-05 31, is a 3.5 KB text file.

Use Cases

• Implementing phase alignment for multi-sensor matrices based on the described allpass filter architecture.
• Reducing computational overhead in embedded telemetry systems based on the zero-heap, zero-copy design.
• Studying fixed-point filter implementations based on the Q16.16 format and saturation clamping described.
• Benchmarking low-power signal processing techniques based on the described current draw management.

Strengths

• Zero dynamic memory allocation, bounded entirely within physical registers.
• Implements 32-bit hardware saturation clamping to prevent integer wrap-around errors.
• Uses 64-bit integer registers for intermediate products to minimize truncation noise.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is very small (3.5 KB), indicating limited scope, likely containing source code or specifications rather than large-scale data.
