Design of key technology in reflective memory network communication module

On the hardware platform of Distributed Real-Time Simulation, a communication module based on reflective memory network was realized in FPGA. As an infrastructure module, it could be integrated with other modules seamlessly. Under the speed-first rules, DMA engine in PCI Master mode was designed, and 64bits/32bits bus compatibility was realized. In order to solve the competition problems during network and memory access, the Arbiter strategy based on adjustable time slice was proposed. In addition, network command packets of higher priority were introduced to fit practical simulation requirements, including the interrupts issue.
