Telestream™ - Grumman's Distributed, Parallel Telemetry Processing System

Abstract

TeleSTREAM™, the GrummanData Systems Corporation telemetry processor, is a hierarchically arranged combination of hardware, firmware and software which can meet the current and future needs for real time processing of telemetry data. The basic design of the system is highly flexible, allowing application to a wide range of user requirements with a minimum of software changes. The logical flow of input, process, output is accomplished by a distributed processing method utilizing three subsystems: Front End Controllers (FEC's); Task Oriented Processors (TOP's); and Output Processors (OP's). Multiple sources can be processed concurrently, with the FEC's selecting specified data words for processing. Typical telemetry processing tasks are handled by a parallel arrangement of table driven processors (TOP's) utilizing a combination of assembly language and microcoded routines. Output processing routes completed buffers of data to a variety of output devices. Additionally, setup, control, diagnostics and status servicing of telemetry formatting equipment is performed by the OP's. A telemetry compiler allows the user to describe to the system the processing requirements of a particular data source and produces the tables utilized by TeleSTREAM™ to handle the parameters.
