Conflict and Hidden Trouble of Distributing Misplay at Memory Resources

摘要

Resources of memory are frequently used times without number for reducing cost of control system. Rewriting in memory would cause occasional hardware conflict when especial data are inputted or are calculated, thereby system faults even accidents are elicited. Origin of occasional malfunction was analysed in automatic control system, necessity of program storage separate from data storage was discussed, and the notion was put forward that resource allocation of memory should be compatible with the system function. So dead halt owing to codes cover each other could be avoided, and reliability of measurement or control system could be effectively improved.
