摘要：A reconfigurable processor architecture. A reconfigurable processor is an arrayof a multiplicity of various functional elements, between which the interconnections maybe programmably configured. The inventive processor is implemented on a singlesubstrate as a network of clusters of elements. Each cluster includes a crossbar switching

node to which a plurality of elements is connected via ports. Additional ports on thecrossbar switching node connect to the switching nodes of nearest neighbor clusters. Thecrossbar switching nodes allow pathways to be programmably set between any of theports, and any pathway may be set to be either registered or unregistered. The use ofclusters of processing elements allows complete freedom of local connectivity foreffective configuration of many different processing functions. Wide area interconnectionis more restricted, but, since it is less used, does not significantly restrict configurability.The inventive processor thus provides 1) high configurability with a low cost of switchingnetwork overhead; 2) constant clock speed, independent of configuration; and 3) veryhigh clock speed since all communication is local or nearest neighbor.
