Mini-NOVA: A Lightweight ARM-based Virtualization Microkernel Supporting Dynamic Partial Reconfiguration

Today, ARM is becoming the mainstream family of processors in the high-performance embedded systems domain. In this context, adding a run-time reconfigurable FPGA device to the ARM processor into a single chip makes it possible to combine high performance and flexibility. In this paper, we propose a low-complexity design of system virtualization running on the Zynq platform. Virtualization of software and hardware resources are managed by a custom microkernel. The dedicated features to efficiently manage the dynamic partial reconfiguration (DPR) technology are described in details. The performance of the DPR management is evaluated and presented at the end of this paper.
