Designing many-core systems for intensive signal processing applications necessitates refreshing common practices in the design of Electronic Design Automation (EDA) tools. This should change the focus of the EDA community from old-fashioned foundations including heavy implementations and time-consuming simulations, to recent engineering practices promoting rapid design and acceptable accuracy. Hence, the challenge of the EDA community comes to define a design process for many-core systems which enables four goals: modeling conciseness, estimation accuracy, design rapidity, and exploration flexibility. In this scenario, the modeling task can be defined as a delicate design phase that requires choosing the adequate Model of Computation (MoC) at each step of the design process. Design models at each level of abstraction provide the basis for applying analysis, synthesis or verification techniques. Since modeling concepts and techniques can have a large influence on the quality, accuracy and rapidity of results, models and corresponding abstraction levels should be well-defined with clear and unambiguous semantics. In this paper, we aim to provide an analysis and comparative overview of common MoCs used in the specification and performance analysis of intensive signal processing applications and many-core architectures. After identifying conventional classifications, we propose a new taxonomy of MoCs based on their purpose in the design flow. The heterogeneity of MoCs in EDA tools is also discussed and various tools are reviewed and compared.
