About the Event

Processors are not perfect. Even the most modern, thoroughly verified processors contain imperfections. Processor imperfections, being embedded in the lowest layer of the system, pose a significant problem not only for software developers during design and debug, but also serve as weaknesses to the security mechanisms implemented in the upper layers of the system. With such a pervasive impact on computing systems, it is vital that processor vendors address these imperfections in a way that maintains the abstraction of a perfect processor promised to software developers.

In this talk, I will present my work on designing systems that help reinforce the abstraction of a perfect processor in the face of a range of processor imperfections. Specifically, we build three reference systems targeted at different design-time processor imperfections: malicious circuits inserted into the processor description, errata-like bugs, and a subset of errata-like bugs that threaten the security abstractions of the processor.
