Abstract: In view of the requirement of Quality of Service(QoS) realization mechanism and strict dynamic priority arrangement, this paper introduces a kind of heap sort algorithm for FPGA realization easily in the exchange system design. The algorithm which unifies the modulation and the condition machine is used to produce the module design mentality, the emulator executes by using XilinxISE8.2i+ModerSim6.2, and the procedure downloads the experiment developping board to validate the system. The result indicates that the design has a high utilization rate of resources and a quick speed of operating. It is suitable for the realization of outstanding QoS mechanism in hardware.
