Zero-Heap Fixed-Point Logarithmic Gain Compressor: C++ Implementation for DSP

A 4.4 KB C++ implementation of a fixed-point logarithmic gain compressor designed by Jamie Davis. The module is structured under the Davis Logic V2 framework for deterministic performance in hard real-time environments. It was last updated on May 31, 2026.

Use Cases

• Benchmarking deterministic DSP algorithms based on the described zero-heap, zero-copy pipeline.
• Testing fixed-point arithmetic performance on hardware without FPUs based on the Q16.16 format.
• Developing real-time audio or telemetry processing modules based on the branchless bit-scan approximation strategy.

Strengths

• Implementation enforces a strict zero-heap allocation footprint for predictable execution.
• Core math operations use 64-bit wide registers to prevent overflow, as described.
• The code is licensed under CC-BY-4.0, allowing for open reuse and modification.

Limitations

• The dataset is very small at 4.4 KB, indicating limited scope, likely containing only source code.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for data analysis tasks.
