Abstract
Systems and methods are disclosed for detecting a deadlock in a cyclical dependency between a set of the plurality of nodes in a mesh network. In some aspects, each of the nodes having a stall detection circuit. The stall detection circuit of each of the nodes operates by providing a stall output that is asserted not only when linked input and output pipeline circuits are stalled but when a stall input from an upstream node indicates that the upstream node is stalled. The stall output is provided as a stall input to the downstream node. In this manner, the stall outputs of the stall detection circuits are stable and asserted when there is a deadlock in a cyclical dependency between a closed loop of nodes in the mesh network.
