Patent number: 11838211Abstract: A system, and corresponding method, is described for finding the optimal or the best set of routes from a master to each of its connected slaves, for all the masters and slaves using an interconnect, such as a network-on-chip (NoC). Some embodiments of the invention apply to a class of interconnects that utilize a two-dimensional mesh topology, wherein a set of switches are arranged on a two-dimensional grid. Masters (initiators or sources) inject data packets or traffic into the interconnect. Slaves (targets or destinations) service the data packets or traffic traveling through the interconnect. The interconnect includes switches and links that are part of a path. Additionally, one or more optimal routes, which is defined by the system, move the traffic in a way that avoids deadlock scenarios.Type: GrantFiled: July 27, 2022Date of Patent: December 5, 2023Assignee: ARTERIS, INC.Inventors: Youcef Bourai, Syed Ijlal Ali Shah, Khaled Labib
