在高能物理实验数据获取系统中使用VME改造原有CAMAC系统可以在花钱不多的前提下显著提高数据获取速度,减少系统死时间。本文介绍了VME-CAMAC混合系统的关键设备之一,带有MC68000微处理器的智能CAMAC分支驱动器的硬件和软件。
Using VME to transform the original CAMAC system in high-energy physics experimental data acquisition system can significantly improve the data acquisition speed and reduce the system dead time under the premise of not spending much money. This article describes the hardware and software for one of the key devices in the VME-CAMAC hybrid system, the smart CAMAC branch driver with the MC68000 microprocessor.
