Exploiting statically schedulable regions in dataflow programs

摘要: Dataflow descriptions have been used in a wide range of Digital Signal Processing (DSP) applications, such as multi-media processing, and wireless communications. Among various forms dataflow modeling, Synchronous (SDF) is geared towards static scheduling computational modules, which improves system performance predictability. However, many DSP applications do not fully conform to the restrictions SDF modeling. More general models, CAL [1], developed describe dynamically-structured applications. Such generalized models can express dynamically changing functionality, but lose powerful capabilities provided by SDF. This paper focuses on detection SDF-like regions dynamic — particular, specification framework CAL. an important step for applying techniques within framework. Our combine advantages different languages tools, including DIF [2] CAL2C [3]. The are demonstrated IDCT module MPEG Reconfigurable Video Coding (RVC).
