Davis Logic V2: Fixed-Point Phase-Locked Loop Loop Filter Implementation

Module 128 from the Davis Logic V2 project details a fixed-point Phase-Locked Loop (PLL) loop filter node designed for bare-metal embedded systems. The component, authored by Jamie Davis and released under a CC BY 4.0 license, implements a zero-heap, zero-copy Proportional-Integral (PI) filter for real-time frequency and phase tracking. The dataset, last updated on 2026-05-31, is a 2.3 KB text file describing the mathematical architecture and computational performance of the filter.

Use Cases

• Implementing a real-time PLL loop filter based on the described Q16.16 fixed-point arithmetic.
• Studying anti-windup and saturation safety mechanisms for control systems based on the hardware-level clamping rules.
• Analyzing memory and performance optimization strategies for bare-metal embedded code based on the zero-heap, zero-copy architecture.
• Benchmarking branch-optimized execution tracks for minimizing dynamic current surges on microcontrollers.

Strengths

• The implementation is explicitly designed for zero-heap and zero-copy operation, eliminating dynamic memory allocation.
• Computational safety is enforced via hardware-level clamping to strict 32-bit signed integer limits to prevent windup.
• The description provides specific performance metrics related to instruction cycle paths and micro-current surges.

Limitations

• The dataset is a 2.3 KB text file, indicating it is documentation or source code, not a traditional data collection for analysis.
• Column-level documentation and sample data are unavailable, making the structure and semantics of any underlying data unclear.
• Row count is unknown, which may limit suitability assessment for machine learning tasks.
