Dev Tutorials

• Setting up a GR4 dev environment
• GNU Radio 4 Core API overview
  - instantiating Blocks
  - adding them to graphs, connecting them and
  - assigning a graph to be executed by a scheduler
  - Merged nodes will be introduced later -> see DevTutorial 3
• Basic to advanced block examples
  • different process_...() forms and their benefits/application
    ...

29. DevTutorial 2: Modern C++ and Advanced Techniques

Dev Tutorials

In this tutorial, we will explore modern C++ features that can be utilized to develop your own blocks and contribute to the GNU Radio 4 project. Specifically, we will focus on std::ranges and std::algorithm, demonstrating their practical applications in everyday tasks. We will highlight the benefits of these modern techniques compared to traditional C++ styles.

Dev Tutorials

• Why should one care? CPU architecture, performance, latency, green computing
• How to think SIMD when using or writing algorithms

31. DevTutorial 4: Compile- and Runtime Performance Debugging Tools

Dev Tutorials

• Advanced techniques for optimising signal processing
  • Focus: High-level algorithms rather than micro-optimisations (to avoid premature optimisations)
• Unit-Testing: good API, functional- to system-integration tests
• Benchmarking, profiling, and debugging tools for developers
  • UT/micro Benchmark facilities
  • run-time: GR4 Profiler framework (uses Google's trace...
