### 5.4 VC路由器的逻辑流水线
1️⃣(BW)head flit到达一个输入端口时,首先<font color="#d99694">根据其输入的VC在BW级进行解码并放入缓冲区</font>
2️⃣(RC)RC级路由逻辑进行计算以<font color="#d99694">确定包的输出端口</font>
3️⃣(VA)head flit在VA级进行仲裁,<font color="#d99694">找到输出端口的VC(即下一个路由器输入端口的VC)</font>
4️⃣(SA)进入SA级,对switch的输入和输出端口进行仲裁
5️⃣(ST)遍历crossbar

6️⃣(LT),该flit被传送到下一个节点
>body和tail flit遵循类似的流水线,但不会经过RC和VA级。而是直接继承header flit分配的路由和VC,tail flit在离开路由器时,会移除head flit保留的VC
