Energy-Efficient Multicore Processor for Large Stream Data in IoT Systems
Reducing energy consumption and keeping high applicability to a variety of applications are contradicting design requirements but both essential for embedded computing devices, especially in IoT era. Contrary to most embedded processors that are getting richer resources for higher performance, we propose multicore processors whose cores individually possess minimum resources. Although such processors are rather computing-inefficient if used as a single-core processor, we utilize multiple cores in a pipeline manner to efficiently handle a large amount of stream data. Also, by adjusting inter-core communications and the number of cores only, our processors achieve not only high throughput and low energy consumption but also good design-productivity. This talk demonstrates some case studies to show the effectiveness of our processors for applications that are often used in IoT systems.
Yuko Hara-Azumi received her Ph.D. degree in information science from Nagoya University in 2010. She was a JSPS postdoctoral research fellow at Ritsumeikan University from 2010 to 2012, during which she was also a visiting scholar at University of California, Irvine, USA and Karlsruhe Institute of Technology, Germany. In 2012, she joined Nara Institute of Science and Technology as an assistant professor. Since 2014, she has been with Tokyo Institute of Technology, where she is currently an associate professor. Her research interests include system-level design automation, especially on high-level and logic synthesis and hardware/software co-design, for embedded/dependable systems. She currently serves as organizing and program committees of several premier conferences including DAC, ICCAD, DATE, ASP-DAC, FPL, and so on.
