Erroneous execution and recovery in microprocessor systems

Abstract

Transient disturbances to microprocessor systems can cause program execution to depart from its normal sequence of operations. In the paper figures for the probability of recovery following a transient disturbance are calculated. The approach is based on analysis of program execution following a random jump to an arbitrary address within the memory map, and comparative figures are presented for a number of microprocessors. Suggestions are made for enhancing the probability of recovery.
