Davis Logic V2 Module 111: Fixed-Point Linear Interpolator and Extrapolator Source Code

Module 111 is a C++ source code file for a zero-heap, zero-copy linear interpolator and extrapolator designed for bare-metal embedded systems. It was authored by Jamie Davis and released under a CC BY 4.0 license, with a last update recorded on 2026-05-31. The 3.7 KB file implements a Q16.16 fixed-point algorithm for real-time data projection and coordinate mapping.

Use Cases

• Compensating for jittery sensor sample rates based on the real-time interpolation capability mentioned in the description.
• Handling intermittent telemetry dropouts based on the extrapolation feature for packet loss events.
• Synchronizing non-uniform logging periods based on the module's function for calculating precise values between known data boundaries.
• Implementing coordinate mapping in resource-constrained environments based on the static memory footprint and integer-only arithmetic.

Strengths

• Memory footprint is explicitly stated as 0 bytes of heap usage, enabling deterministic execution.
• The algorithm uses 64-bit integer registers and 32-bit saturation boundaries to prevent overflow and preserve resolution.
• The source code is openly licensed under CC BY 4.0, facilitating reuse and modification.

Limitations

• The dataset is a single 3.7 KB text file containing source code, not a traditional data collection for analysis.
• Column-level documentation is absent; the file's structure and function must be inferred from the description or by reading the code.
• The description is highly technical and focused on implementation, not on accompanying example data or benchmarks.
