A Radar Signal Processing Case Study for Dataflow Programming of Manycores

摘要: The successful realization of next generation radar systems have high performance demands on the signal processing chain. Among these are advanced Active Electronically Scanned Array (AESA) radars in which complex calculations to be performed huge sets data real-time. Manycore architectures designed provide flexibility and essential for such streaming applications. This paper deals with implementation compute-intensive parts AESA chain a high-level dataflow language; CAL. We evaluate approach by targeting commercial manycore architecture, Epiphany, present our findings terms productivity gains achieved this case study. comparison results reference sequential implementations executing state-of-the-art embedded processor show that we able achieve speedup 1.6x 4.4x using only 10 cores Epiphany.
