An architecture for a reconfigurable network that can be implemented on a semiconductor chip is disclosed, which includes a hierarchical organization of network components and functions that are readily programmable and highly flexible. Essentially, a reconfigurable network on a chip is disclosed, which includes aspects of reconfigurable computing, system on a chip, and network on a chip designs. More precisely, a reconfigurable network on a chip includes a general purpose microprocessor for implementing software tasks, a plurality of on-chip memories for facilitating the processing of large data structures as well as processor collaboration, a plurality of reconfigurable execution units including self-contained, individually reconfigurable programmable logic arrays, a plurality of configurable system interface units that provide interconnections between on-chip memories, networks or buses, an on-chip network including a network interconnection interface that enables communication between all reconfigurable execution units, configurable system interface units and general purpose microprocessors, a fine grain interconnect unit that gathers associated input/output signals for a particular interface and attaches them to a designated system interface resource, and a plurality of input/output blocks that supply the link between an on-chip interface resource and a particular external network or device interface. Advantageously, the network minimizes the configuration latency of the reconfigurable execution units and also enables reconfiguration on-the-fly.
