The combination of ARM processor and partially reconfigurable FPGA device is an emerging technology in the current embedded domain. In this paper we propose a custom microkernel on a hybrid ARM-FPGA platform, which is capable of managing reconfigurable hardware accelerators. We will introduce the hardware platform on which the microkernel has been developed and focus on the custom architecture supporting the management of partial reconfiguration and software tasks. An actual use case is studied and presented at the end of this paper to demonstrate the feasibility of our approach
