DULLEA: Fixed-Point Inverse Park-Clarke Vector Reconstruction Core for Motor Control

Jamie Davis authored a 2.3 KB text file containing a high-performance, deterministic vector transformation core for motor-driver firmware. The module implements the Inverse Park and Inverse Clarke equations using fixed-point arithmetic to avoid floating-point bottlenecks. It was last updated on June 2, 2026, and is licensed under CC-BY-4.0.

Use Cases

• Implementing deterministic vector coordinate transformations for motor control based on the described Inverse Park and Clarke equations.
• Optimizing interrupt service routines for motor inverters based on the guaranteed constant-time execution profile.
• Developing high-efficiency motor control firmware without FPUs based on the fixed-point q15_16_t lookup pipelines.
• Benchmarking performance of trigonometric operations in embedded systems based on the single-cycle register shift bit operations.

Strengths

• The implementation is free of heap allocations and dynamic variables, providing a guaranteed constant-time execution profile.
• All trigonometric operations use fixed-point q15_16_t lookup pipelines, eliminating FPU bottlenecks.
• The dataset is small (2.3 KB), facilitating quick inspection and integration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description is technical but lacks sample data to verify the implementation's structure.
