Abstract
Circuitry is provided that includes programmable fabric with fine-grain routing wires and a separate programmable coarse-grain routing network that provides enhanced bandwidth, low latency, and deterministic routing behavior. The programmable coarse-grain routing network may be implemented on an active interposer die. The programmable fabric may be implemented on a top die that is stacked on the active interposer die. A protocol-based network on chip (NoC) may be overlaid on the coarse-grain routing network. Although the NoC protocol is nondeterministic, the coarse-grain routing network includes an array of programmable switch boxes linked together using a predetermined number of routing channels to provide deterministic routing. Pipeline registers may be interposed within the routing channels at fixed locations to guarantee timing closure.
