Title
Effectively Handling Primary And Backup Overruns And Underruns In A Real-Time Embedded System That Tolerates Permanent Hardware And Software Failures
Abstract
A method and architecture are presented which tolerates both permanent processor failures and permanent software failures by scheduling a primary and a separate backup on different processors for every real-time process, while further increasing system robustness and reliability, by using primary and backup latest start times to effectively handle primary and backup underruns and overruns, both before, and after, a permanent processor failure, which significantly increases the chances that a primary or backup may meet its deadline despite permanent hardware failures and permanent software failures, and despite overrunning, while also satisfying additional complex constraints defined on the primaries and backups such as precedence and exclusion relations, in a fault tolerant real-time embedded system.
