Abstract
In this paper we present an analysis of crosstalk effects on busses implementing error correcting codes.
We show that the redundancy introduced by these codes can be exploited in order to avoid the worst case
crosstalk-induced delay. Our analysis is based on the evaluation of the coupling effective capacitance which
need to be charged during bus activity. In particular, we analyze the cases of the Hamming and Dual Rail
codes. We show that Hamming codes do not allow us to avoid the most delay costly bus transitions, while
this can be the case for Dual Rail codes. Furthermore, we illustrate that, by increasing the redundancy
of the Dual Rail code by only one bit, even higher crosstalk-induced delay reductions can be achieved.
Finally, we show that a further improvement can be obtained by an optimized placing of the bus wires.
