ABSTRACT:
Data-processing systems including processor datapaths that efficiently support computationally advantageous routing operations are disclosed. Data-processing methods based on such systems are also disclosed. An exemplary data-processing system includes a register file, a routing unit, a switch, and an arithmetic logic unit. The arithmetic logic unit may include a bitwise function unit, pipeline register, and an accumulator. The switch may have N data inputs and logM(N) switching stages. M may equal 2 or 4. In the case of log2(N) stages, each switching stage has N/2 switching cells. The routing unit may include a control logic that generates a control signal, and various logics that respectively operate on various bit groups of the control signal.
