US Patent 8261042 Reconfigurable multi-processing coarse-grain array

A signal processing device is adapted for simultaneous processing of at least two process threads in a multi-processing manner. The device comprises a plurality of functional units capable of executing word- or subword-level operations on data. The device further comprises means for interconnecting the plurality of functional units, the means for interconnecting supporting a plurality of dynamically switchable interconnect arrangements, and at least one of the interconnect arrangements interconnects the plurality of functional units into at least two non-overlapping processing units each with a pre-determined topology. The device further comprises at least two control modules each assigned to one of the processing units.
