....signals. Note that these correlations are only the simplest kinds of correlation relations, because they do not model the temporal correlations that can exist in vector streams over several clock cycles. We emphasize this point to indicate that proposed approaches that use correlation coe#cients [9] may be able to handle pairwise correlations between bits in a vector or between consecutive vectors, but cannot handle the variety of other input signal relations that can exist in sequential circuits. In other words, although sequence compaction methods [9] replace the realistic, long vector set ....
....that use correlation coe#cients [9] may be able to handle pairwise correlations between bits in a vector or between consecutive vectors, but cannot handle the variety of other input signal relations that can exist in sequential circuits. In other words, although sequence compaction methods [9] replace the realistic, long vector set with a smaller vector set that satisfies similar statistics, they still run the risk of taking the sequential circuit into illegal states. This is because they might introduce new vectors or vector sequences that take the sequential circuit into illegal ....

....processor ules. To begin, it is known [15] that the most important source of power dissipation in a module is the dynamic charging and discharging of its gates, called the switched capacitance. This switched capacitance is dependent upon the module s input values [14] It has been further shown [13, 6] that the Hamming distance of consecutive input patterns, defined as the number of bit positions that differ between them, provides a suitable measure of power consumption. In [13, 6] power is modeled as: # ( where ....

....a hybrid simulation engine which is able to fully adapt to the application behavior and provide up to 20X better accuracy than the fixed window sampling technique presented previously. Our work complements existing techniques for gate and RT level power estimation based on sequence compaction [11] by recognizing the effect of fine and coarse grain temporal dependencies, present in common software applications. 1.2 Paper Overview and Contributions Our main goal is to accelerate existing simulators, by predicting power and performance values accurately. This scheme can be applied to ....
