Intelligent Input/Output Subsystem for CAMAC and FASTBUS (Physics)

提出了一种模块化智能输入/输出系统的原型，该系统利用CAMAC并行支路和新一代数字设备公司（DEC）的VAXBI总线，为大型复杂实验提供数据采集系统之间的接口。该设计将利用基于微处理器的控制器NMOS T414，该控制器在传输到VAXBI总线之前对数据进行预处理，从而释放主计算机的中央处理器用于其他任务。子系统的速度和本地智能将允许实时完成更大比例的数据处理。通过实时处理，数据采集系统和实验可以定时进行，最大限度地提高实验效率。该系统有望对以极高速率收集大量数据的能力产生重大影响，这在实验物理的许多领域都很重要，但在高能物理中尤为重要。

The proposal is to construct and test a prototype of a modular intelligent input/output system which is to provide the interface between data acquisition systems for large and complex experiments using the CAMAC Parallel Branch Highway and the new generation Digital Equipment Corporation (DEC) VAXBI bus. The design which has been worked out will utilize a microprocessor-based controller, the NMOS T414, which preprocesses data prior to transmission to the VAXBI bus, thus freeing the central processor of the main computer for other tasks. The subsystems speed and local intelligence will allow a greater proportion of data processing done in real time. With the real-time processing, the data acquisition system and the experiment can be timed to maximize the experimental effectiveness. The proposed system is expected to have a significant impact on the ability to collect a large amount of data at extremely high rates, which is of importance in many areas of experimental physics, but in particular in high energy physics.
