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.

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.

Abstract: Methods and systems for configuring a programmable logic device include receiving configuration data at an input of a first sector of the programmable logic device and dynamically routing the configuration data through the first sector to a second sector of the programmable device by selecting a first routing path out of the first sector or a second routing path out of the first sector.

Abstract: In a first mode, a control circuit can implement a circuit design with storage circuits in an integrated circuit by programming configuration memory bits via configuration resources. The storage circuits can be accessed for read and write operations during execution of the implemented circuit design with the integrated circuit. In a second mode, the control circuit can perform read and write access operations at the storage circuits via configuration resources or via an interface circuit and interconnect resources that are allocated to the circuit design implementation. Typical applications for performing access operations at the storage circuits include fault injection and observation, statistical monitoring of the circuit design, initialization and the distribution of certain signals such as reset signals, event sampling, just to name a few.

Abstract: In server virtualization, the resources of an integrated circuit are partitioned into smaller portions, and each of these smaller portions is then operated independently. Software is used to represent the smaller portions as virtual environments. For the purpose of server virtualization, an integrated circuit may include several different circuit designs, each implemented in a secure partition in the integrated circuit. The operation of the circuit design implementations in the integrated circuit may require that each circuit design implementation can be verified as un-altered and from the respective user or owner and as having been approved by the integrated circuit owner and/or the circuit design implementation owner. The operation of the circuit design implementations in the integrated circuit may require that each circuit design implementation can be operated securely and independently of the other circuit design implementations in the integrated circuit.
