METHOD AND SYSTEM FOR IMPROVED DEFFERENTIAL FORM OF TRANSITIONAL CODING

摘要

PROBLEM TO BE SOLVED: To provide a method and system for differential transmission of data on a bus overcoming the limitations of conventional systems. SOLUTION: This differential transitional coding uses a differential bus. Use of differential transition includes a step to divide a differential bus into one or more groups each of which is composed of four bus lines. Use of a differential bus includes a step to assert half of the bus lines in one group during bus data transmission and thereby regulate the asserted and reversely asserted sets of the bus lines. In addition, at least one of the bus lines in the asserted set is reversely asserted and at least one of the bus lines in the reversely asserted set is asserted. Consequently, data are differentially transmitted by driving two bus lines, i.e., one line for one set. COPYRIGHT: (C)2004,JPO
