Davis Logic V2: Fixed-Point Alpha-Beta Predictive Tracking Filter

2.2 KB of production-hardened C++ source code for a Fixed-Point Alpha-Beta Predictive Tracking Filter, part of the Davis Logic V2 DULLEA framework. Authored by Jamie Davis, this module is engineered for deterministic, low-latency state estimation on bare-metal architectures. The dataset was last updated on June 1, 2026.

Use Cases

• Smoothing position and velocity sensor data based on the module's state estimation capabilities.
• Implementing high-frequency target trajectory tracking for radar or optical flow systems as described.
• Integrating deterministic, low-overhead filtering into multi-axis robotic limb positioning control loops.

Strengths

• Code is explicitly designed for zero heap allocations, guaranteeing uniform execution cycle latency.
• Implements bit-shift scaling using 64-bit integer registers, making it independent of a Floating-Point Unit (FPU).
• Published under a permissive CC-BY-4.0 license, facilitating integration into commercial and open-source projects.

Limitations

• The dataset is very small at 2.2 KB, indicating it is a single source code module with limited scope.
• Column-level documentation is absent; the data structure and API must be inferred from the code after download.
• Row count is unknown, which may limit suitability assessment for those expecting a traditional data table.
