Basic building blocks for asynchronous packet routers

QNoC asynchronous router

“…ViChaR [37] performs dynamic allocation of VCs according to traffic conditions. Asynchronous packet routers for off-chip networks were presented as early as 1994 [38]. CHAIN [8] [9] is proposed as an asynchronous interconnect for NoC that is not a 2D mesh.…”

An Asynchronous Router for Multiple Service Levels Networks on Chip

“…Synchronous routers using round-robin arbitration and supporting asynchronous interconnect are presented in [9] [10], though synchronization issues are ignored. Asynchronous packet routers for off-chip networks were presented as early as 1994 [11]. Synchronous NoC routers supporting virtual channels, which could be used to provide multiple service levels, are described in [12] and [13].…”
