ResumoA basic processing system based on the Z8000 processor is described as part of a small ground to air defence system. Its basic response to induced bus errors is analysed. This leads to the use of Recovery Block software techniques as well as hardware watchdog timers and traps, to increase the system availability during fault conditions. Results are presented which show significant improvement in performance for 15-20% software and execution time overhead.
