Watchdog processors in parallel systems
A watchdog processor (WDP) is a relatively simple coprocessor built for concurrent, information compaction based error detection in the main program control flow.A new algorithm called SEIS (Signature Encoded Instruction Stream) is presented for assigning signatures to high levelinstructions. The main idea of this method is to embed the information necessary to the program flow check into the s...
متن کاملMultiprocessor Checking Using Watchdog Processors
A new control flow checking scheme is presented, based on assigned-signature checking using a watchdog processor. This scheme is suitable for a multitasking, multiprocessor environment. The hardware overhead is comparatively low because of three reasons: first, hierarchically structured, the scheme uses only a single watchdog processor to monitor multiple processes on multiple processors. Secon...
متن کاملNew Formulation and Solution in PCB Assembly Systems with Parallel Batch processors
This paper considers the scheduling problem of parallel batch processing machines with non-identical job size and processing time. In this paper, a new mathematical model with ready time and batch size constraints is presented to formulate the problem mathematically, in which simultaneous reduction of the makespan and earliness-tardiness is the objective function. In recent years, the nature-in...
متن کاملHierarchical Checking of Multiprocessors Using Watchdog Processors
A new control flow checking scheme, based on assigned-signature checking by a watchdog processor, is presented. This scheme is suitable for a multitasking, multiprocessor environment. The hardware overhead is comparatively low because of three reasons: first, hierarchically structured, the scheme uses only a single watchdog processor to monitor multiple processes or processors. Second, as an as...
متن کاملConcurrent Error Detection Using Watchdog Processors - A Survey
A bstract-This is a survey of concurrent system-level error detection techniques using a watchdog processor. A watchdog processor is a small and simple coprocessor that detects errors by monitoring the behavior of a system. Like replication it does not depend on any fault model for error detection. However, it requires less hardware as compared to replication. It is shown that a large number of...
