Davis Logic V2: Fixed-Point Interpolator and Bare-Metal SPI Driver Code

Two advanced operational layers for a bare-metal processing ecosystem, designed to eliminate data packet drops and scheduling delays in critical environments. The dataset includes a Cubic Hermite Spline spatial interpolator and a low-level Serial Peripheral Interface hardware bus driver module, both implemented without a floating-point unit or dynamic memory heap. It was authored by Jamie Davis and published on figshare in 2026.

Use Cases

• Implementing sub-millimeter coordinate path smoothing for tracking systems based on the described Cubic Hermite Spline interpolation engine.
• Developing low-jitter, high-frequency sensor data capture routines based on the bare-metal SPI hardware register driver.
• Benchmarking fixed-point arithmetic performance for real-time systems that cannot rely on a floating-point unit.
• Creating reference architectures for deterministic, heap-free execution in safety-critical embedded environments.

Strengths

• The components are engineered for deterministic, clock-cycle invariant execution, a critical feature for real-time systems.
• Includes both a spatial interpolation engine and a physical hardware driver, covering two key layers for sensor data processing.
• Released under a permissive Creative Commons Attribution 4.0 International license.

Limitations

• The dataset is very small at 6.0 KB, suggesting it is likely source code or documentation rather than a large collection of observational data.
• Row count and column-level documentation are absent; the structure and semantics of any included data must be inferred after download.
• Description metadata is limited to the purpose and components; actual implementation quality requires manual code inspection.
