DSPiga

DSPiga is a digital signal processing library written in the C programming language. Its primary focus is to provide a collection of efficient and well-tested algorithms for common signal processing tasks. The library aims to be portable and easy to integrate into various embedded systems and applications where computational resources might be constrained.

The core functionalities of DSPiga include routines for filtering, such as Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) filters. It also offers implementations for Fourier transforms, including the Fast Fourier Transform (FFT) and its inverse, enabling frequency domain analysis. Additionally, DSPiga provides functions for windowing, correlation, and other signal manipulation techniques.

Development of DSPiga emphasizes performance and accuracy, making it suitable for real-time applications. The library is designed with a modular structure, allowing developers to select and use only the necessary components, thereby minimizing code size and memory footprint. Its C-based nature contributes to its broad applicability across different hardware platforms. While not as feature-rich as some larger, more comprehensive DSP frameworks, DSPiga offers a solid foundation for fundamental signal processing operations in resource-limited environments. The project is typically available under an open-source license, encouraging community contribution and adoption.
