摘要: A coherent attached processor proxy (CAPP) that participates in coherence communication a primary system on behalf of an external maintains, each plurality entries CAPP directory, information regarding respective associated cache line data from the cached by processor. In response to initiation recovery operations, transmits, generally sequential order with respect multiple memory access requests indicating error for addresses indicated entries. snooped request targets particular address hitting directory during transmitting, performs operation prior time order.
