PROJECT TITLE :
Characterizing Vulnerability of Network Interfaces in Embedded Chip Multiprocessors
ABSTRACT :
In Networks-on-Chip (NoC), with ever-increasing style complexity and technology scaling, soft errors have become a key style challenge. During this work, we tend to extend the concept of architectural vulnerability issue (AVF) from the microprocessor domain and propose a network vulnerability factor (NVF) to characterize the susceptibility of Network Interfaces (NIs) to soft errors. For the primary time, an in depth characterization of vulnerability is performed on a state-of-the-art AXI-primarily based NI design using full system simulation. Our studies reveal that different NI buffers behave quite differently within the presence of transient faults and every buffer will have different inherent tolerance to faults. Our analysis additionally considers the impact of thermal hotspot mitigation techniques on the NVF estimation.
