摘要
A combined scalar and vector processing system is provided including a scalar XI directory which records the lines currently being stored into by the scalar processors and vector store register devices (VSR) which record lines currently being stored into by vector processors wherein both vector and scalar XI requests are compared to those addresses stored in the vector store register devices. If there is a compare at a VSR, any responses normally provided from the scalar XI directory are held until the vector store register device receives a release signal from the vector processor indicating said vector processor is finished to thereby prevent the scalar processors from fetching invalid data.
