ii Models and Methods for Development of DSP Applications on Manycore Processors

iii Advanced digital signal processing systems require specialised high-performance embedded computer architectures. The term high-performance translates to large amounts of data and computations per time unit. The term embedded further implies requirements on physical size and power efficiency. Thus the requirements are of both functional and non-functional nature. This thesis addresses the development of high-performance digital signal processing systems relying on manycore technology. We propose building two-level hierarchical computer architectures for this domain of applications. Fur-ther, we outline a tool flow based on methods and analysis techniques for automated, multi-objective mapping of such applications on distributed mem-ory manycore processors. In particular, the focus is put on how to provide a means for tunable strategies for mapping of task graphs on array structured distributed memory manycores, with respect to given application constraints
