Pufferspeicher-Betriebsverfahren

摘要

The invention concerns a method of operating buffer storage systems in multi-processor central processing units with coupling by means of bus systems. The data transfer of an input-output system acting on a memory array which is located exclusively in a buffer memory is first interrupted, produces the marking PURGED, and then brings about re-writing in the main memory, whereupon the marking changes to INVALID and the interrupted data transfer can be repeated.
