Interconnect 的 Corelink NIC-400 指的是什么呀？ 这和 AHB/AXI 是什么关系呢？
Corelink NIC-400 是ARM的一个interconnect IP, 用于连接bus master和slave的。 AHB/AXI只是用于总线协议。

About the CoreLink NIC-400 Network Interconnect
The CoreLink NIC-400 Network Interconnect is highly configurable and enables you to create a complete high performance, optimized AMBA® compliant network infrastructure. The possible configurations for the CoreLink NIC-400 Network Interconnect can range from a single bridge component, for example an AHB™ to AXI protocol conversion bridge, to a complex interconnect that consists of up to 128 masters and 64 slaves of AMBA protocols.
The NIC-400 configuration can consist of multiple switches with many topology options. Figure 1.1 shows a top-level block diagram of the NIC-400 that contains:
