IntegerSignal

A header-only C++ library for efficient integer-only signal processing and response curves, defined using templates for speed and (compile-time) flexibility.

Features

  • Integer-only Arithmetic: No floating point operations, compatible and fast even on 8 bit MCUs.

  • Templates and Inheritance: Filters and Curves are compile time chainable, making it simple do define custom filter types.

  • Filters: Includes implementations of EMA (Exponential Moving Average) and DEMA (Double Exponential Moving Average).

  • Curves: Includes implementations for power^2, power^2, root^2. Square root operations are hardware accelerated on ARM architectures (CLZ).
