Abstract: Power supply voltages are selectively modulated to correspond with degraded input voltages to a logic device. Modulated power supply voltages are provided to transistors within the logic device, so that the degraded input voltages supplied to the transistors are sufficient to turn the transistors substantially on or off. Leakage currents are prevented thereby from flowing across the transistors.

Abstract: A heterogeneous array includes clusters of processing elements. The clusters include a combination of ALUs and multiplexers linked by direct connections and various general-purpose routing networks. The multiplexers are controlled by the ALUs in the same cluster, or alternatively by ALUs in other clusters, via a dedicated multiplexer control network. Components of applications configured onto the array are selectively implemented in either multiplexers or ALUs, as determined by the relative efficiency of implementing the component in one or the other type of processing element, and by the relative availability of the processing element types. Multiplexer control signals are generated from combinations of ALU status signals, and optionally routed to control multiplexers in different clusters.

Abstract: The invention relates to a reconfigurable device comprising a plurality of processing devices, a connection matrix providing an interconnect between the processing devices, and means to define the configuration of the connection matrix. Each of the processing devices comprises an arithmetic logic unit, which is adapted to perform a function on input operands and produce an output. The input operands are provided as inputs to the arithmetic logic unit from the interconnect on the same route in each cycle. Dynamic instructions are enabled by means provided to route the output of a first one of the processing devices to a second one of the processing devices to determine the function performed by the second one of the processing devices.
