Abstract: In this paper, we propose a technique for lowering th e latency of the communication in a NoC (network on chip). The technique, which can support two qualities of service (QoS), i.e., the guaranteed thr oughput (GT) and best effort (BE), is base d on splitting a wider link into narrower links to increase throughput and decrease latency in the NoC. In addition, to ease the syn-chronization and reduce the crosstalk, we use the 1-of-4 encoding for the smaller buses. The use of the encoding in the propose d NoC architecture considerably lowers the latency for both BE and GT packets. In addition, the bandwidth is increased while the power consumption of the links is reduced.


摘要 在本文中,提出一種對(duì)于通訊網(wǎng)絡(luò)在其國(guó)家或地區(qū)(芯片) 的低延遲技術(shù)。應(yīng)用該技術(shù)既可支持這兩種特質(zhì)的服務(wù)(QoS)，即保證吞吐量(GT)和最佳的狀態(tài)(BE)，是基于分裂更廣泛的鏈接到較窄的鏈接來增加吞吐量和減少延遲。此外，為了緩解同步和減少噪聲，用1-4編碼為較小的運(yùn)載工具。該編碼的使用使得國(guó)家或地區(qū)大大降低了延遲，即是GT的數(shù)據(jù)包。此外，也使帶寬增加，用電環(huán)節(jié)減少。
