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.
