Abstract

1. Software-Directed Energy Optimization for Embedded NoC Architectures

 Network-on-Chip (NoC) based systems are becoming increasingly popular due to scalability and flexibity they bring. In this talk, I will present the work going on at Penn State in reducing energy consumption of NoCs under compiler control. The specific techniques I will discuss include link shutdown,link voltage/frequency scaling, and link reuse. I will also discuss the experimental results that compare the compiler-directed methods to pure hardware-based ones.

2.Compiler-Directed Solutions to Transient Hardware Errors

Ever-scaling process technology combined with heavily used power reducing techniques results in an increase in transient hardware errors. While circuit techniques and architectural mechanisms are critical to cope with these errors, software can be more effective and flexible in resource constrained embedded systems. I will present an overview of the compiler-directed reliability work being done at Penn State and discuss important issues that need to be tackled in the future.
