The Development of a Real-Time Integration Processing Technique for PCM data between Asynchronous Master and Slave Telemetry

Abstract

In this paper, we describe the development of a real-time integration processing technique for PCM data between asynchronous master and slave Telemetry. In a synchronization parallel processing method of a real-time integration processing technique, the slave encoder receives a DSSP(Dual Sync Start Pulse) as a reference start pulse from master encoder and synchronizes the clock by generating the clock synchronized with master encoder to overcome the limitation of synchronization processing time between asynchronous master and slave Telemetry. The slave encoder transmits processed PCM data according to synchronization clock of slave encoder to master encoder. The master encoder outputs integrated PCM data in real time. After implementing the synchronization parallel processing method, we prove that the designed logic operates normally using signal tap. Also, we verify that data real-time integration processing is possible within one frame cycle through processing time test.
