This paper presents an optical interconnect model for kary n-cube network topologies based on free-space analysis. This model integrates relevant parameters inherent to optics wit...
Signature based error detection techniques (e.g. the application of watchdog processors) can be easily extended to support software debugging. The run-time sequence of signatures ...
