Design of ATM Switch Control Chip Based on Resource Budget

The system bottleneck caused by bus bandwidth and memory space can be encountered until the stage of register transfer level coding design,and that will increase the design iteration.Aiming at this problem,budgeting technique for system resources is used.This paper aims to decide the parameters of Asynchronous Transfer Mode(ATM) switch chip based on hardware resource occupied during the process of switch.Simulation and hardware test results indicate the ATM switch chip can meet the system’s requirements.
