summary

Describes CEDR, an open-source Linux user-space compile-time and run-time ecosystem for mapping streaming software-defined radio graphs onto heterogeneous SoCs (example: Zynq UltraScale MPSoC). Covers a thread-per-processing-element scheduling model, pipelined execution with work queues, reservation-based resource management, and use of imitation learning (regression trees, neural nets) to train schedulers; includes demonstrations measuring execution time, throughput and resource use with Radar and WiFi workloads and examples of plug-and-play accelerator and scheduler integration.
