A GENERAL APPLICATION REAL TIME PROCESSING AND DISPLAY SYSTEM

Abstract

A general purpose system for the processing and display of telemetry data is described. The system uses a DEC PDP-11 mini-computer as the system processor. Systems of this type implemented in the past generally had limited data processing capabilities due to high data rates and limited CPU power. The Real Time Data Monitor System (RTDMS) is designed to maximize the data processing capability by teaming the CPU with a pre-processor. A total hardware/ software system was designed which is structured around certain commonly required classes of data. The system minimizes the processor overhead associated with each class thereby freeing time for useful processing. A complete software system was implemented which takes full advantage of the RSX-11M multi-task operating system. Because of the substantial data base required to configure the system, particular attention was given to the operator interface. A set of programs were implemented which construct all data base files required using interactive menus. Operator input is minimized as well as the training time required to set-up the system.
