Data coding methods for low-power aided design of submicron interconnects

We present in this paper a CAD tool that aims at designing low-energy buses. The Graphical User Interface (GUI) we developed manages many techniques dealing with the addressed problem: simple coding, coding subject to fixed/dynamic probabilities and an enhanced dynamic probabilities-based technique. Moreover, this environment allows tuning the parameters of data encoding/decoding and is able to generate different gains by varying the size of the bus transferring the encoded data. Thus, this tool is suitable for efficiently designing telecommunication and multimedia systems that are strong data consumers and can be easily configured to integrate new coding techniques, then using one of them when favorably compared against the other techniques.
