Protection Structures in Multithreaded Systems [PDF]

open access: yesThe Computer Journal, 2012
We consider a single-address-space system which implements a form of segmentation with paging within the framework of the multithreaded model of program execution. A salient problem of a system of this type is the definition of the set of mechanisms enforcing memory protection. We present a paradigm for the protection system design that is based on the
