PROJECT TITLE :
PRUNE: Dynamic and Decidable Dataflow for Signal Processing on Heterogeneous Platforms - 2018
The majority of latest mobile devices and private computers are based mostly on heterogeneous computing platforms that incorporates a variety of CPU cores and a number of graphics processing units (GPUs). Despite the high volume of those devices, there are few existing programming frameworks that concentrate on full and simultaneous utilization of all CPU and GPU devices of the platform. This article presents a dataflow-flavored model of computation (MoC) that has been developed for deploying signal processing applications to heterogeneous platforms. The presented MoC is dynamic and allows describing applications with data dependent run-time behavior. On top of the MoC, formal design rules are presented that enable application descriptions to be simultaneously dynamic and decidable. Decidability guarantees compile-time application analyzability for deadlock freedom and bounded memory. The presented MoC and the planning rules are realized in a novel Open Supply programming surroundings “PRUNE” and demonstrated with representative application examples from the domains of image processing, pc vision and wireless communications. Experimental results show that the proposed approach outperforms the state-of-the-art in analyzability, flexibility, and performance.
