Mapping data-intensive applications to an explicitly managed memory architecture: Challenges and solutions

In this talk, we will present our experience of mapping complex, data-intensive applications on the STMicroelectronics STHORM (aka Platform 2012) many-core fabric, which uses an explicitly managed memory (EMM) architecture. An EMM architecture was chosen as a means to achieve low-power and high-performance solutions. We present a top-down, applications-to-platform mapping perspective, highlight the multiple levels of efficient movements of data across a complex EMM hierarchy. We will use data-centric computer vision and image analytics applications to illustrate the issues and potential solutions. We discuss the lessons learned and research directions for next-generation MP-SoC mapping tools.
