To address this problem, this paper develops new modeling and analysis techniques based on dataflow representations, and demonstrates these techniques on a multi-core implementation case study involving multiple, concurrently-executing image processing applications. Our techniques are based on careful representation and exploitation of frame- or block-based operations, which involve repeated invocations of the same computations across regularly- arranged subsets of data. Using these new approaches to manage block-based image data, this paper demonstrates methods to analyze synchronization overhead and FIFO buffer sizes when mapping image processing applications onto heterogeneous, multi core architectures.}, keywords = {block-based image data, buffer memory management, buffer storage, concurrently-executing image processing application, data flow computing, data flow representation, data subset, Dataflow, Digital signal processing, Energy consumption, Energy management, Engineering management, FIFO buffer sizes, Hardware, Image analysis, IMAGE PROCESSING, image processing application, image representation, interprocessor communication, memory architecture, Memory management, multiapplication image processing, multicore image processing, multiprocessing, on-chip memory, power consumption, power consumption overhead, Runtime, scheduling, set theory, shared memory, storage management chips, synchronization overhead}, author = {Ko,Dong-Ik and Won, N. and Bhattacharyya, Shuvra S.} }
