IPC: H04L12/40
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To identify accurately read data outputted for a period of T-sec based on a measured real value by measuring the length of H and L level of consecutive 0s and 1s. SOLUTION: Plural slave sets S1 , S2 ,... S8 are connected by bus connection with common lines L1 , L2 . When a bit level remains H or L level and there is no level change, it is discriminated to be binary data 0. When a bit level includes H and L level and there is any level change, it is discriminated to be binary data 1. In the case of sending/receiving read data between a master set and a slave set, binary test data of consecutive 0s and consecutive 1s are sent from one of master and slave sets to the other. The other of the master and slave sets receiving the binary test data measures the length of consecutive 0s and consecutive is being H and L levels and identifies real data based on the measured real value.
