A hardware implementation of capability-based addressing

Abstract

The SWARD architecture, an experimental higher-level architecture, contains the naming and protection concept of capability-based addressing. After discussing the merits of capability-based addressing, its general representation in the SWARD architecture is discussed. The initial representation of capability-based addressing in the architecture led to a set of problems; these problems are described, as well as their solutions. Finally, the implementation of capabilities by the processor is discussed.
