英文摘要Network-on-Chip (NoC) is a promising replacement of bus architecture due to its better scalability. In state-of-the-art NoCs, each packet contains several fixed-length flits, which facilitates allocations of network resources but brings in many unused bits. In this paper, we propose a novel technique called Stealth-ACK to effectively address the above problem. Stealth-ACK leverages unused bits in head flits of non-ACK packets to carry and stealthily transmit ACK information. Such stealth transmissions of ACK information effectively reduce not only the amount of dedicated ACK packets on NoC, but also the number of unused bits in head flits of non-ACK packets, which significantly reduces wastes on NoC bandwidth. Experimental results show that Stealth-ACK averagely increases the throughput of 16 x 16 2-D mesh NoC by 11.9%, and averagely reduces the NoC latency by 34.8% on application traces of SPLASH-2. Moreover, Stealth-ACK only requires trivial hardware modification to basic router architectures, which incurs negligible power consumption and area cost.
