A Cache Design for a Security Architecture for Microprocessors (SAM)
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
In this paper we present a cache design for a secure combined hardware and software architecture called SAM. ...
Additionally, the cache has to consider different memory views and protection levels as well as support for protected shared memory, a key feature of SAM. ...
Conclusion In this work we presented a cache design suitable for the SAM architecture. ...
