DATA TRANSFER CONNECTION BETWEEN A PRIMARY DEVICE AND A PLURALITY OF SECONDARY DEVICES WITH A REDUCED NUMBER OF LINKS

摘要

The primary device (DSP) is connected to m x n secondary devices (ESLIC1-4) by one data link (IOB) comprising the m x n data channels assigned to respective secondary devices (ESLIC1-4) say m clock links (GKCO-1 ) connected to m respective groups each of n secondary devices (ESLIC1-3; ESLIC2-4) and carrying m clock signals having a same clock frequency and being mutually shifted by 1/mth of a cycle of the clock frequency, and by n read/write links (RDO-1) connected to n respective groups each of m secondary devices (ESLIC1-2; ESLIC3-4) and carrying n read/write signals mutually shifted by one cycle of the clock frequency, each secondary device (ESLIC1-4) belonging to a distinct pair of one group out of the m groups (ESLIC1-3; ESLIC2-4) and of one group out of the n groups ( ESLIC1-2; ESLIC3-4).
