Separable allocators in on-chip routers perform switch allocation in two stages that often make uncoordinated decisions resulting in sub-optimal switch allocation. We propose Virtual Input Crossbars (VIX), where more than one virtual channel (VC) of an input port is connected to the crossbar. VIX improves switch allocation by allowing more than one input VC(More)
