A SYSTEM OF MICROPROCESSORS CONNECTED TO A SERIES DATA BUS

摘要

In a process for interconnecting microprocessors, a master microprocessor (1) transmits a character. All the slave microprocessors receive it in a register (4). If processing is in progress in the slave (2) for which it is intended, the character is masked until the processing is finished. After the processing, the slave microprocessor (2) recognizes it, removes it from the register (4) and loads this latter with an echo intended for the master microprocessor (1), allowing it to transmit a new character.
