On the Necessity of Combining Coding with Spacing and Shielding for Improving Performance and Power in Very Deep Sub-micron Interconnects

摘要

In this work, the necessity of combining signal encoding schemes with low-level anti-crosstalk techniques like spacing and shielding is analyzed. It is shown that in order to increase the throughput improvement and/or reduce the power consumption, coding schemes should be integrated with layout techniques since methods like spacing and shielding can be regarded as very simple encoding schemes. On this basis, a theoretical framework for assessing the improvement in throughput and/or power consumption is constructed. Furthermore, several possibilities to integrate coding with classical anti-crosstalk techniques are discussed.
