Performance of CAMAC I/O with an HP A600
The ability to transfer large quantities of data in a short period of time between computers and front-end instrumentation is very important in experiments where transient data acquisition is performed. The Mars project at Lawrence Livermore National Laboratory is such an experiment. We need to transfer 64 Kbytes of data from a multichannel data logger to an HP A600 computer. In order to maintain the overall performance guidelines of the data acquisition system, we need to transfer the 64 Kbytes of data in one second or less. To meet the data transfer requirement each component in the communication path must be least meet, and preferably exceed, the required data transfer rate. These components include an HP A600 CPU operating under RTE-A.1, an HP 12009A HPIB interface card, the GPIB instrumentation bus, a GPIB-CAMAC crate controller, and a LeCroy 8212A-32 data logger. In configuring the system to meet the above requirement, we found it necessary to analyze the performance of each component in the communication path.
