Abstract

During normal operation in a buffer-backing store system, when the CPU sends a fetch request, the data is returned to the CPU from the cache, if it is available. If the requested data is not in the cache, main storage is cycled, and the data is written in the cache and also sent to the CPU. In this configuration, when diagnostics are run, they will be loaded into main storage and then executed out of main storage and the cache.
