Event Recording System in Large Scale Distributed Parallel DSP Processing

This paper focuses on the monitoring and debugging issues of concurrent DSP processing system in real time large scale distributed parallel scenario. It strives for putting the record and replay technique which stems from the parallel computing realm, into practice for modern high performance embedded computing (HPEC) application and enhancing its feasibility and scalability. Architecture of event recording system based on high performance DSP COTS modules is established, and its core components are designed and implemented, including global clocking domain, event generator and event recorder.
