Abstract

DETECçãO DE VULNERABILIDADE DE ARQUITETURA DE RECURSOS DE PROCESSADOR. A presente invenção provê, em uma modalidade, uni detector de quantum para detectar uma medida de vulnerabilidade para um processador baseado em uma métrica de processador, cada uma associada à operação de unia estrutura de processador durante um quantum, junto com um controlador para controlar uma unidade de mitigação de erro com base na medida de vulnerabilidade. Outras modalidades são descritas e reivindicadas.
