FPGA Virtualization Mechanism Based on Heterogeneous Zynq Platforms

FPGA (Field Programmable Gate Array) has the advantages of parallelism and reconfigurability, therefore, it is widely used in areas such as image processing, robotics and artificial intelligence. However, the development of FPGA currently involves too many hardware details, so it lacks extensibility for different platforms and flexibility for system level management and scheduling. In this paper, we propose an FPGA Virtualization Mechanism (FVM), which divides physical resources into pages (virtual resources). We use the technology of PR (Partial Reconfiguration) and the method of intermediate form to lift the extensibility and performance. We implement FVM in our platform VSC (Vary Super Computer System). Experiment results show that FVM can solve the problem of extensibility and flexibility, with high performance.
