摘要：A method for synchronising communication of a plurality of data processingunits over data bus (3) is disclosed. Each of the data processing units (1, 2) comprising

local clock oscillators (6) providing clock signals for synchronising digital data

communication. A first data processing unit is provided as a master data processing unit(1) synchronising the timing for data communication and controlling the data

communication of controlled slave data processing units (2). The bit length of a sequenceof bits to be communicated over the data bus (3) is dynamically adapted to adjust a clockcycle difference between a master clock cycle based upon the local clock oscillator signalof the master data processing unit (1) and a slave clock cycle based upon the local clockoscillator signal of a slave data processing unit (2).
