Crosstalk effect minimization for encoded busses

Crosstalk effect minimization for encoded busses
Crosstalk effect minimization for encoded busses
In this paper we present a technique which allows to reduce the crosstalk-induced delay within busses implementing an error detecting/correcting code. This technique is based on the observation that the maximum delay on an encoded bus is usually due to the check bits that are added to provide the desired error detection/ tolerance ability. These bits, in fact, are computed from the bus information bits by an ad hoc encoder, which adds an extra delay to the crosstalk-induced bus delay. We will show that, by proper placement of the lines carrying the information with respect to those carrying the check bits, it is possible to reduce the effective coupling capacitance due to the Miller effect among adjacent lines. This allows a reduction of propagation delay which, depending on the implemented code, can overcome the 20% with respect to the conventional placement of encoded busses

Abstract

In this paper we present a technique which allows to reduce the crosstalk-induced delay within busses implementing an error detecting/correcting code. This technique is based on the observation that the maximum delay on an encoded bus is usually due to the check bits that are added to provide the desired error detection/ tolerance ability. These bits, in fact, are computed from the bus information bits by an ad hoc encoder, which adds an extra delay to the crosstalk-induced bus delay. We will show that, by proper placement of the lines carrying the information with respect to those carrying the check bits, it is possible to reduce the effective coupling capacitance due to the Miller effect among adjacent lines. This allows a reduction of propagation delay which, depending on the implemented code, can overcome the 20% with respect to the conventional placement of encoded busses
