ABSTRACT:
A virtual memory management system for a vector based processing system detects early page or segment faults allowing pipelined instructions to be halted and resumed once the pages or segments required for a job are available in main storage. A multiplier is used for stride accesses, and min and max registers are used for gather/scatter instructions to provide a range of addresses to be accessed during a job. These ranges are determined early enough in execution of instructions related to a job to allow saving the state of the processor and resuming execution of the instructions once the data is available in main storage.
