Abstract: Resource sharing in modern chip multiprocessors (multicores) provides many cost and performance benefits. However, component sharing also creates drawbacks for fault, performance, and security isolation.Thus, integration of components on a multicore chip should also be accompanied by features that help isolate effects of faults, destructive performance interference, and security breaches.
