摘要
提出了８０９８单片机双机共享存储器系统的设计方法。该方法全部由硬件实现，不须软件配合，且硬件结构简单，易于实现，适用于９６系列的单片机，讨论了用ＧＡＬ器件来实现硬件裁决的设计过程，并分析了８０９８单片机读写公共存储器的时序。
A design method for dual microcontroller system with a type 8098 single -chip comput-er using a shared memory is presented.The method is implemented entirely hardware.The structure is simple and no special software is needed.It is suitable for the MCS-96 fami-Iy of l6-bit microcontrollers.The design of a hardware arbitrator using a GAL chip is alsodescribed.The time sequencing of access to the shared memory is discussed.
