  • Multiprocessor system with memory fetch buffer invoked during cross-interrogation
    Patent number: 5032985
    Abstract: An improved multiprocessor system of the type including a plurality of processors and an array of memories interconnected by an interrogation logic where the processors have a store-in cache is presented. In such processors the most recent copy of the data does not always reside in the memories but can reside in a processor's cache necessitating cross-interrogation producing system delays. These delays are reduced by a fetch buffer selectively coupled to each memory for holding data before cross-interrogation and other checks are complete.
