Abstract
A data transmission system includes a host CPU having an output terminal for repeatedly producing a predetermined number of data blocks in a predetermined sequence in a repeated manner. Each data block is defined by a sequence code for identifying each data block and specific data followed by the sequence code. A plurality of slave CPUs are provided. The host CPU is connected to each slave CPU through a bus structure for the mutual data transmission. Each slave CPU receives all the data blocks and selectively extracts only the necessary data for use in each slave CPU and produces data from its output terminal at a given period within one cycle of the predetermined sequence. The given period for one slave CPU differs from that of another slave CPU, thereby transmitting data to the host CPU without any interferences.
