In order to solve the problem of the limitation of hardware resource consumption on the satellite onboard switch, this paper implements a kind of queue manager circuit, and introduced the design ideas, working process of each module. Key modules are programmed and realized with Verilog HDL. The results of ModelSim former simulation show that the circuit satisfies the functions of queue management equipment which is of high efficiency in cell switching.

Abstract-This paper implements a shared memory switching structure with multicast function due to the demand of multicast function on the satellite onboard switch, introduced each module of the ideas and working process in detail. Key modules are programmed and realized with Verilog HDL. The results of ModelSim former simulation show that the circuit satisfies the functions of the shared memory swapping structure, and requirements with low complexity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
