INTEGRATED DATA PROCESSING CIRCUIT WITH A PLURALITY OF PROGRAMMABLE PROCESSORS

摘要

An integrated data processing circuit contains matrix of programmable processors. Each processor (12) has private operand transfer connections to its neighboring processors (12) in the matrix, typically for passing operands of transfer commands. An additional tree communication structure contain router circuits (16, 18, 19) hierarchically coupled to each other and to the processors. The processors (12) form leave nodes of the tree structure, the router circuits (16, 18, 19) being arranged to route a message with an address from a root router (19) circuit to an addressed processor (12), selectively via a path through the tree structure, the router circuits (16, 18, 19) each selecting a part of the path under control of the address.
