HW-SW Management Using a Lightweight Yocto-based OS Running on a ZCU102

This work presents the development of a lightweight OS based on Yocto that has been extended to support the transparent management of HW accelerators. The accelerator is defined using the tool called MDC and, then, the co-processor (connecting the processor and the HW accelerator) is automatically generated together with a set of dedicated APIs to manage the accelerator.

This procedure is validated in the context of Comp4Drones ECSEL JU project, implementing and accelerating a soil segmentation algorithm on the ZCU102 FPGA architecture, reaching speedups up to 1.55x with real images from the artichoke field.
