System-Level Design of Resilient Multiprocessor System-on-Chip

Abstract

Technology scaling due to decreasing size of transistors has led the transition from single superscalar processors to multiprocessor system on chip (MPSoC) in a wide range of critical cyber-physical systems (CPS), including unmanned ground and air vehicles and SmartGrid, and thereby critically depend on the reliability and dependability of micro-and nano-electronic components. While software faults used to be the main source of concern, for example in automotive electronic systems, digital hardware has become a main source of faults since about 2010. This is due in particular because of feature size of integrated circuits approaching 10 nm horizontally and single layers of atoms vertically. As result, the long-term dependable service of multi-core processor in safety-critical applications is no longer guaranteed. Resilience-aware computing aims at designing and deploying systems that can withstand the successful exploitation of vulnerabilities and continue to meet mission goals. In the effort to reduce development cost and time-to-market, MPSoC designs are trending towards a heavy utilization of third-party Intellectual Property (IP) cores. Besides the challenges of correct integration of components from different vendor, this outsourcing of IP design to a third-party opens the door for potential introduction of malicious components. Traditional fault tolerant systems that uses redundancy based on probability of component failure fall short to address future challenges, due to the difficulty of verifying the probability of attack and successful exploitation of system vulnerability.
This talk addresses system-level-design of secured MPSoC through a tighter integration of user-specified resiliency requirements and objectives in the hardware/software design process. The talk discusses generic models and tools to capture and quantify resiliency in MPSoC, along with protocols that automatically generate the hardware/software security infrastructure.
