Davis Logic V2: Deterministic Fixed-Point Square Root Core for Embedded Systems

Jamie Davis authored a 1.5 KB text file containing a deterministic fixed-point square root core for 32-bit bare-metal architectures. The module, named DULLEA, is designed for constant-time execution on platforms like ARM Cortex-M, ESP32, and STM32. It was last updated on June 2, 2026, and is licensed under CC-BY-4.0.

Use Cases

• Calculate multi-axis vector magnitudes for inertial navigation based on the algorithm's deterministic execution.
• Scale radar signal telemetry based on the module's fixed-point arithmetic and 64-bit scaling buffers.
• Implement sensor data transformations in hardware interrupt layers based on the sub-microsecond predictability described.

Strengths

• File size is precisely 1.5 KB, indicating a compact, focused implementation.
• The description specifies the algorithm eliminates floating-point unit dependencies and standard math library overhead.
• The core is engineered for constant-time execution to eliminate input-dependent jitter, a key feature for real-time systems.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description is technical but lacks sample data or concrete performance benchmarks.
