    • Methods and apparatuses are described for a communication system. The communication system may include one or more initiator agents, where each agent couples to its own Intellectual Property core. The communication system may also include two or more target agents, where each agent couples to its own Intellectual Property core. The communication system may also include an interconnect using an end-to-end width conversion mechanism. The conversion mechanism converts data widths between the initiator agent and a first target agent. Two or more branches of pathways in the interconnect exist between the initiator agent and the two or more target agents. The conversion mechanism to use a lookup table that includes data width information of the initiator agent and the two or more branches of pathways to the two or more target agents to concurrently pre-compute width conversion signals for each of the target agent branches.
    • 对于通信系统描述了方法和装置。 通信系统可以包括一个或多个启动器代理,其中每个代理耦合到其自己的知识产权核心。 通信系统还可以包括两个或多个目标代理,其中每个代理人耦合到其自己的知识产权核心。 通信系统还可以包括使用端对端宽度转换机制的互连。 转换机制转换启动器代理和第一个目标代理之间的数据宽度。 在引发剂和两种或多种目标试剂之间存在互连途径中的两个或更多个通路分支。 使用查找表的转换机制,其包括发起者代理的数据宽度信息和到两个或更多个目标代理的路径的两个或更多个分支以同时预先计算每个目标代理分支的宽度转换信号。

    • Various methods and apparatuses are described in which an interconnect couples to a plurality of initiator network resources and a plurality of target network resources. The interconnect may include a first stage of circuitry, a second stage of circuitry, and an arbitration controller. The first stage of circuitry receives incoming transactions from the plurality of initiator network resources. The second stage of circuitry passes outgoing transactions to the plurality of target network resources connecting to the interconnect. The arbitration controller arbitrates transactions from the plurality of initiator network resources destined to one or more of the target network resources. The target network resources supply their availability to service a transaction to the arbitration controller. The arbitration controller implements an arbitration policy that filters out transactions from the arbitration process those transactions from initiator network resources destine to target network resources that are currently not available to service a transaction.
    • 描述各种方法和装置,其中互连耦合到多个发起者网络资源和多个目标网络资源。 互连可以包括第一级电路,第二级电路和仲裁控制器。 电路的第一阶段从多个发起者网络资源接收传入的事务。 电路的第二阶段将输出事务传递到连接到互连的多个目标网络资源。 仲裁控制器仲裁来自指定给一个或多个目标网络资源的多个发起者网络资源的事务。 目标网络资源将其可用性提供给仲裁控制器。 仲裁控制器实施仲裁策略,从仲裁过程中过滤出来自发起者网络资源的那些事务指向当前不可用于服务于事务的网络资源的目标网络资源。
