    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 fabric may be implemented on a top die that is stacked on the active interposer die. The programmable coarse-grain routing network and smart memory circuitry may be implemented on an active interposer die. the smart memory circuitry may be configured to perform higher level functions than simple read and write operations. The smart memory circuitry may carry out command based low cycle count operations using a state machine without requiring execution of a program code, complex microcontroller based multicycle operations, and other non-generic microcontroller based smart RAM functions.

    Abstract: A three dimensional circuit system includes first and second integrated circuit (IC) dies. The first IC die includes programmable logic circuits arranged in sectors and first programmable interconnection circuits having first router circuits. The second IC die includes non-programmable circuits arranged in regions and second programmable interconnection circuits having second router circuits. Each of the regions in the second IC die is vertically aligned with at least one of the sectors in the first IC die. Each of the second router circuits is coupled to one of the first router circuits through a vertical die-to-die connection. The first and second programmable interconnection circuits are programmable to route signals between the programmable logic circuits and the non-programmable circuits through the first and second router circuits. The circuit system may include additional IC dies. The first and second IC dies and any additional IC dies are coupled in a vertically stacked configuration.

    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.
