路由器缓冲区在片上网络的整体操作中起着重要作用。除了性能之外，缓冲区对网络的整体能量预算也有很大的影响。事实上，在构成soc互连结构的不同组件中，缓冲器是NoC路由器中最大的泄漏功率消费者，消耗了约64%的路由器总泄漏功率[50]。同样，缓冲区也会消耗大量的动态功率[22,51]，并且随着数据包流量的增加，这种消耗会迅速增加。事实上，据观察，在缓冲区中存储一个数据包所消耗的能量远远超过传输该数据包所消耗的能量。此外，片上路由器所占用的区域主要由缓冲区控制[14,52,53]。因此，缓冲器设计在构建高性能和节能的片上互连中起着至关重要的作用，也是本节的重点。
Router buffers are instrumental in the overall operation of the on-chip network. Besides performance, buffers greatly affect the network’s overall energy budget. In fact, of the different components comprising the interconnection fabric of SoCs, buffers are the largest leakage power consumers in an NoC router, consuming about 64% of the total router leakage power [50]. Similarly, buffers consume significant dynamic power [22,51] and this consumption increases rapidly as packet flow throughput increases [51]. In fact, it has been observed that storing a packet in a buffer consumes far more energy than transmitting the packet [51]. Furthermore, the area occupied by an on-chip router is dominated by the buffers [14,52,53]. Consequently, buffer design plays a crucial role in architecting high performance and energy efficient on-chip interconnects, and is the focus of this section.
