ABSTRACT:
A dedicated hardware block is provided for implementing crossbars and/or barrel shifters in programmable logic resources. Crossbar and/or barrel shifter circuitry may replace one or more rows, one or more columns, one or more rectangles, or any combination thereof of programmable logic regions on a programmable logic resource. The functionality of the crossbar and/or barrel shifter circuitry can further be improved by implementing time-multiplexing.
