DATA TRANSFER NETWORK AND CONTROL APPARATUS FOR A SYSTEM WITH AN ARRAY OF PROCESSING ELEMENTS EACH EITHER SELF-OR COMMON CONTROLLED

A processor of SIMD/MIMD dual mode architecture comprises common controlled first processing elements, self-controlled second processing elements and a pipelined (ring) network connecting the first PEs and the second PEs sequentially. An access controller has access control lines, each access control line being connected to each PE of the first and second PEs to control data access timing between each PE and the network. Each PE can be self-controlled or common controlled, such as dual mode SIMD/MIMD architectures, reducing the wiring area requirement.
