Title: User satisfaction metric based NOC performance optimization
Speaker: Swamy Ponpandi, Ph.D. Candidate, Iowa State University
Abstract: Mobile computing platforms have become ubiquitous execution engines for a wide range of applications such as audio/video decoding, gaming, e-commerce, cloud based technology. Raw computational power demand of such applications has led to the development of innovative multi-core architectures. Homogeneous and heterogeneous architectures with more than one computational core is the current hardware solution to tackle power and performance requirements of mobile OS and applications. Embedded system design based on multi-core architecture needs to address issues related to on-chip communication, abstraction of computation and resource allocation to satisfy design constraints. Network-on-chip (NOC) communication paradigm is a versatile interconnect architecture which is scalable and supports the bandwidth needs of mobile applications. Resource allocation in NOC based embedded system is often statically determined. This results in sub-optimal utilization of system resources. User satisfaction tries to model the dynamic resource needs of applications from an end users perspective. In this talk, I will review NOC communication model for multi-core architecture and user satisfaction based resource allocation strategy to optimize performance.
