报告摘要：
Embedded systems are everywhere in our everyday lives and driving an information revolution. Using heterogeneous functional units (FUs), I have addressed high-level architecture synthesis for real-time embedded systems. With more and more different types of FUs available, same type of operations can be processed by heterogeneous FUs with different costs, where the cost may relate to power, reliability, etc. Furthermore, some tasks may not have fixed execution time. Such tasks usually contain conditional instructions and/or operations that could have different execution times for different inputs. Therefore, for such special purpose architecture synthesis, an important problem is how to assign a proper function unit type to each operation of embedded systems and generate a schedule in such a way that I can minimize the total costs while satisfying timing constraints with guaranteed confidence probabilities. I have proposed several efficient algorithms to solve this problem. The experiments show that my algorithms can effectively reduce the total cost compared with the previous work. I also have applied this approach for low power design and multi-bank on-chip memory to improve the performance and energy-saving of the systems. A lot of novel results have been produced and most of them have already been reported to research community through high-quality journal (such as ACM Trans. on Design Automation (TODAES), ACM Trans. on Embedded Computing Systems, IEEE Trans. on Computer, and IEEE Trans. on VLSI) and conference papers (ACM/IEEE DAC, DATE, and ISSS+CODES).
