In the last decade the GNU Radio project and its ecosystem has grown a lot. Unfortunately not all parts of the project have got attention equally. A lot of new and missing functionality can be found in so-called Out-of-Tree modules (OOTs). The struggle to add changes to OOTs which are incompatible to the GNU Radio core is real. The GNU Radio runtime needs some fresh ideas so new development with GNU Radio will be possible and rewarding. This presentation will try to give an quick overview about the current structure and inner workings of the GNU Radio runtime and take a dive into how a new runtime can be implemented to make GNU Radio future-proof.
