Partitioned Bus-Invert Coding for Power Consumption Optimization of Data Bus
For VLSI design in deep submicron technology, the bus energy reduction becomes more and more important In this paper, we modify the bus-invert coding method to maximize the power consumption reduction of data bus. Unlike the conventional scheme in which the whole bus lines are considered for bus-invert coding, our scheme partitions the bus lines into several subbuses and each partitioned sub-bus is coded independently by bus-invert coding method. For an 8bit data bus the bus-invert coding method can reduce at least 25% power consumption, while the traditional bus-invert method is 18.75 %.
