ABSTRACT:
A digital signal processor (24) includes a plurality of vector processors (212x), each of which is made up of a group of, for example, six signal processors (214x). Each signal processor includes Local 1 and Local 2 ports (201, 203), and the Local 1 port of one processor of a group is coupled by a path (218) to the Local 2 port of another processor, so the group forms a ring. Each signal processor (214) also includes a memory (234), an arithmetic processor (232), and a switcher (230) for making internal interconnections among the ports, and also includes a switcher control (364, 366). At least one of the signal processors (214) of each group is of a type including a further external port (206), by which data can be coupled by a path (105) to and from the group. The signal processors of each group can be interconnected for serial or parallel processing, all under the control of a group controller (216) associated with each vector processor.
