Gag, T. Wegner, and D. Timmermann Simulation Accuracy Traditional data independent power estimation considers a transition probability of 50 %. In Fig. 2 the results of our system level power estimation compared to a traditional one are shown. In addition, we determined the estimated power values with the actual gathered transition probability without calculating crosstalk effects to rule out the influence of the MCF. As expected, the highly compressed data mostly consists of uncorrelated patterns.

1. 2 Dynamic Power Flip-flops are used in wide variety of circuits targeting different applications where the data rates could be different. Therefore, it’s important to study the power consumption of the flip-flop with respect to the switching activity of data input or data rate (which also results in change in the output state). Here, dynamic Power is measured with respect to different data rates and a constant clock frequency. 3 Static Power As leakage power has become quite significant in submicron technologies, it is also important to know what current flip-flop is drawing in inactive state.

97% Table 4. 41 Conclusions In this paper the low-power technique of multi-Vdd design has been applied for the design of multiply-add units in residue number system. It is shown that the particular technique can be used in RNS systems because the paths defined by the moduli channels are clearly distinguished and the designer can easily apply high- and low-voltage areas in the design. Residue Arithmetic for Designing Low-Power Multiply-Add Units 39 Furthermore, binary and residue multiply-add units are quantitatively compared.
