Fuchs, W.

There are several applications for which backward execution is useful. In an environment where reliability is a concern, it may be necessary to roll back the program to a previously executed state in case of system faults. Multiple instruction retry is an alternative to checkpointing for recovery from a transient processor failure, especially when the error detection latency is only a few cycles. Speculative execution can achieve significant speedup for superscalar architectures by utilizing instruction retry to roll back the computation above mispredicted branches. Debugging is another field that can benefit from backward execution. Allowing the user to undo several instructions at specific positions may facilitate program debugging. This thesis describes schemes that have been implemented for multiple instruction retry for both RISC-type scalar processors, and very long instruction word (VLIW) architectures. The thesis also presents approaches that incorporate backward execution into a debugger, at both the compiler and the debugger levels. Made available in DSpace on 2011-05-07T13:18:50Z (GMT).
