Virtual channel designs for guaranteeing bandwidth in asynchronous network-on-chip

Asynchronous design of networks-on-chip

“…This leads to conclusions which support asynchronous implementation of NoC routers and links. Section V reviews the implementation of a couple of asynchronous NoCs designed at DTU [7], [8], [9], [10], [11], [12], [13], and finally section VI concludes the paper.…”

QNoC asynchronous router

“…NoCs have been studied intensively recently [7]- [15], [29]- [33]. Several NoC implementations have been published and fabricated.…”

“…The MANGO [13]- [15] router explores VC usage for hard service guarantee routing in combination with BE routing. The MANGO router comprises two sub-modules, a non-blocking switch for hard guarantee service (GS) packets and another for BE packets.…”

Packetizing OCP Transactions in the MANGO Network-on-Chip

“…VC control [5] ensures that a flit can only gain access to a link, if the target VC buffer is free, hence once access is granted, the flit will experience no congestion. Therefore t link is constant [6].…”
