    • Systems and methods for trace multicast across a bus structure are provided. Preferably, the bus structure is that of a System-on-a-Chip (SoC), where the SoC includes a number of master components and a number of slave components connected via the bus structure. The bus structure supports a trace multicast feature. In one embodiment, the bus structure receives a bus transaction from a master component and, in response, outputs the bus transaction to a corresponding slave port. In addition, the bus structure determines whether a trace multicast is desired for the bus transaction. If a trace multicast is desired, the bus structure generates an additional bus transaction having one or more transaction attributes that include a translated version of the bus transaction and outputs the additional bus transaction to a trace slave port of the bus structure. The trace multicast feature provides a non-invasive mechanism for driver-level trace.
    • 提供了通过总线结构跟踪组播的系统和方法。 优选地,总线结构是片上系统(SoC)的结构,其中SoC包括多个主组件和通过总线结构连接的多个从组件。 总线结构支持跟踪组播功能。 在一个实施例中,总线结构从主组件接收总线事务,并且作为响应,将总线事务输出到对应的从端口。 此外,总线结构确定对于总线事务是否需要跟踪多播。 如果需要跟踪多播,则总线结构生成具有一个或多个事务属性的附加总线事务,该事务属性包括总线事务的转换版本,并将附加总线事务输出到总线结构的跟踪从站端口。 跟踪多播功能为驱动程序级跟踪提供了非侵入性机制。
