Abstract

In this paper, we propose two systematic coding schemes for a low-power multiple-valued current-mode (MVCM) asynchronous communication link. The goal of the proposed coding schemes is to realize a low power MVCM asynchronous communication link by reducing the summation of values in codeword which is corresponding to the summation of static current flows in the circuits. The summation of values of systematic coding-based codeword (which includes data word and delay insensitive (DI) field) is determined by the maximal summation of the original data word. The proposed two coding schemes reduce the maximal summation of values of the data word by inverting each bit of the data word and extracting common-element (or minimal value) of the data word when appropriate. Comparison with the conventional coding schemes, the proposed coding schemes reduces the average of the summation of the code words to almost half.
