Abstract

A data coding system that compresses data and enables data, e.g., prefix addresses, to be represented with significantly fewer memory cells when compared to conventional coding systems.

Claims (4)

1. A data coding method comprising the steps of:

adding a first bit to a first portion of a data entry having a length of w bits,

determining a first value representing the number of don't care (DC) bits that are adjacent to the first bit;

setting the value of the first bit and each adjacent bit that is a DC bit except for last DC bit, to indicate that the adjacent bit is a DC bit.
