| Abstract: | In order to solve the sequence mismatching problem between PCI 9052 and dual-port RAM,a design that employs FPGA to implement the interface circuit between them is proposed.The design can make the system more compact.The core logic part of this system is implemented with Finite State Machine(FSM),which makes the control logic simple and intuitive,and efficient.The design is validated by ModelSim Se,the simulated waves obtained are in accordance with the requirement. |
