Abstract: The invention is a transaction interface protocol wherein the interface protocol has a transaction identifier signal in each of the request and response channels. It is used between a target network interface unit (NIU) master and an initiator NIU slave that are directly connected through a transaction interface. The target NIU response channel uses the transaction ID signal to identify the entry in a context array associated with the corresponding request. The coupling of target NIU and initiator NIU enable the formation of an on-chip interconnect comprising multiple network-on-chip (NoCs) wherein the topology of the interconnect is simpler, smaller, faster, and has lower latency.

Abstract translation: 本发明是事务接口协议，其中接口协议在每个请求和响应信道中具有事务标识符信号。 它在目标网络接口单元（NIU）主机和通过事务接口直接连接的启动器NIU从站之间使用。 目标NIU响应信道使用事务ID信号来识别与相应请求相关联的上下文阵列中的条目。 目标NIU和启动器NIU的耦合使得能够形成包括多个片上网络（NoC）的片上互连，其中互连的拓扑更简单，更小，更快，并且具有更低的延迟。
