  author={Adam Wiggins and Simon Winwood and Harvey Tuch and Gernot Heiser},
  booktitle={Asia-Pacific Computer Systems Architecture Conference},
Fine-grained hardware protection, if it can be done without slowing down the processor, could deliver significant benefits to sof tware, enabling the implementation of strongly encapsulated light-weight obj ects. In this paper we introduce Legba, a new caching architecture that aims at sup porting fine-grained memory protection and protected procedure calls without sl owing down the processor’s clock speed. This is achieved by separating translation from protection , which allows the use of… CONTINUE READING
