摘　　要：提出了一种应用于多CPU控制系统的串行总线多主机通讯模式,它是在I2C总线通讯协议的基础上加以改进的,并利用普通的8051单片机的I/O口进行串行通信,节约了硬件资源,简化了电路设计。在智能家庭终端的设计中使用,取得良好的效果。A muti- host communication mode based on serial bus is proposed in this paper. The communication mode can be used in muti- CPU control system. The communication manner is developed on the base of I^2C serial communication protocol and can be used in common 8051 MCU system. We can use I/O pin of 8051 MCU to realize this serial communication mode to save hardware source and simplify the circuit design. The design is used in intelligent home device.
