HzXz

HzXz is a fictional open-source software framework designed for real-time signal processing and analytics. The project provides a modular data-flow architecture that allows users to build processing pipelines by connecting independent components called modules. HzXz aims to deliver low-latency performance across desktop and embedded platforms while maintaining a simple plugin interface.

Origin and naming: HzXz appeared in technical fiction and in stylized open-source exercises intended to illustrate pipeline architectures. The name combines Hz, a unit of frequency, with Xz as a symbolic placeholder for extensibility and experimentation.

Architecture and features: The core consists of a scheduler, a graph compiler, and a runtime that executes connected modules. Modules declare their input and output ports and can be implemented in C++, with Python bindings provided to support rapid prototyping. The framework uses a lock-free data queue and supports multi-threaded execution, synchronization primitives, and real-time priorities. HzXz includes a library of standard modules for filtering, Fourier transforms, normalization, and visualization, as well as a plugin API for third-party extensions.

Applications: HzXz is described as suitable for audio processing, sensor data analysis, robotics, and academic demonstrations of data-flow programming. It is used in educational materials and in demonstration projects within simulated environments.

Reception: In the fictional context, HzXz is noted for its balance of performance and extensibility, though its ecosystem and formal documentation remain limited compared to established frameworks.
