Linux as the Conductor - Driving Pre-Compiled Audio DSP Kernels on C7x for Real-Time Processing - Vishnu Pratap Singh - ADCx India 2026
---

This talk is about how Linux can efficiently offload real-time audio processing to TI’s C7x DSP cores without rewriting DSP algorithms. The C7x runs pre-compiled audio DSP kernels, while Linux acts as the controller—streaming audio buffers, triggering DSP execution, and retrieving processed data through RPMsg and shared memory. Using TI Sitara SoC , we talk about two example workflows: audio frame processing offload and 2D-FFT acceleration. Attendees will learn the buffer-exchange model, IPC setup, latency considerations, and deployment steps needed to enable reliable heterogeneous compute where ARM orchestrates and DSP executes.
