摘要
ATM传输是宽带综合业务数字网的重要技术,为使DSP能接入ATM系统,利用TMS320C64x特有的UTOPIA接口构建了一个ATM系统的从设备。介绍了UTOPIA接口基本的发送和接收操作流程,设计了与主控制器MPC8260连接的接口电路,重点探讨了UTOPIA从设备端的参数设置要点,并给出部分程序段代码。
ATM transfer is an important technology of Broadband Integrated Services Digital Network （B-ISDN）, in order to have access to ATM system for DSP, a slave device of ATM system is constructed by using a special UTOPIA interface of TMS320C64x.Basal transmit and receive operation of UTOPIA interface is described,an interface circuit is designed, in which MPC8260 is used for the master device, parameter setting of UTOPIA slave device is mainly discussed, and some program segments are provided as reference.
