buffer invalidation
缓冲无效
In a System／370 multiprocessing configuration intercommunication between processing units to ensure that all real storage references by both processing units access the most recently stored data. Data placed in the high-speed buffer of one processing unit is broadcast to the other processing unit; if the data is also being maintained in its high-speed buffer, that obsolete version of the data is marked invalid.
IBM System／370多道配置中处理部件之间的内部通信,以确保两个处理部件都按实际存 储器地址存取最新储存的数据。存放在一个处理部件高速缓冲区内的数据被传播给其它处理 部件;如果这些数据已在高速缓冲区内,则这个过时的数据文本被标无效。 |
