Propagating reconfiguration command over asynchronous self-synchronous global and inter-cluster local buses coupling wrappers of clusters of processing module matrix

摘要

A semiconductor device includes a plurality of processing clusters that operate synchronously internally and arranged in a M×N matrix. Each processing cluster is formed as a plurality of processing elements and clocked buses that interconnect the processing elements within each processing cluster. A self-synchronous cluster wrapper is operative with the processing elements such that each processing cluster forms a programmable module. Self-synchronous global and local buses interconnect the processing clusters for communicating externally. An input/output circuit interconnects the global and local buses.
