Abstract: 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.

摘要： 内部总线带宽和存储器容量的限制可能导致系统瓶颈，且在寄存器传输级代码设计阶段才能被发现，增加了设计迭代次数。针对该问题，利用系统资源预算技术，通过分析异步传输模式(ATM)信元在交换过程中占用的各种硬件资源确定ATM交换芯片设计过程中的各项参数。仿真与硬件测试结果表明，该芯片能满足系统工作要求。
