Davis Logic V2: Fixed-Point Exponential Moving Average (EMA) Filter Core (DULLEA)

Abstract

Davis Logic V2: DULLEA Ecosystem Module 024: Fixed-Point Exponential Moving Average (EMA) Filter Core A highly deterministic, zero-allocation infinite impulse response (IIR) filtering kernel engineered for single-sample low-pass smoothing and noise reduction across high-rate physical sensor channels on 32-bit bare-metal architectures (ARM Cortex-M, ESP32, STM32). Key Architectural Details: - Minimizes memory footprint by maintaining only a single historical data state register, completely removing the array buffer requirements of standard rolling filters. - Executes all scaling actions entirely within the q15_16_t fixed-point domain using configurable alpha smoothing constants. - Avoids runtime hardware division blocks by utilizing high-efficiency inline arithmetic bit-shifts during historical attenuation loops. Conforms strictly to freestanding C++ rules, eliminating dynamic allocations to guarantee fixed, constant-time cycle latency in sub-microsecond hardware interrupt p ipelines.
