5. 19. Hardware and Software Mechanisms for Control Flow Checking

   Författare :Ghassem Miremadi; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; error detection latency; signature monitoring; watchdog processor; dependability evaluation; transient faults; physical fault injection; concurrent error detection; control flow checking; error detection coverage;

   Sammanfattning : The improvement of dependability in computing systems requires the evaluation of fault tolerance mechanisms such as error detection, error recovery and reconfiguration. Central to this thesis is an experimental evaluation of several hardware and/or software implemented mechanisms for the concurrent detection of control flow errors. LÄS MER

7. 20. Technology Driven Obsolescence Management for Embedded Systems

   Författare :Xiaozhou Meng; Benny Thörnberg; Mattias O'Nils; Jim Tørresen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Long life cycle; embedded system; DMSMS; obsolescnece; FPGA; IP; portability;

   Sammanfattning : In this thesis, the work presented is in relation to technology driven obsolescence management for embedded systems.Component obsolescence problems may occur in systems with a life cycle longer than that of one or more of their components when there is a demand without enough existing stock, such as automotive, avionics, military applications, etc. LÄS MER
