Abstract

The technique to be described provides a combined real/virtual storage mechanism from a common storage pool where a virtual buffer facility uses under-utilized real storage. It can be used with microprocessors with multiple priority interrupt levels where a machine check/program check activates the highest priority interrupt level and where there is no hardware protection to main storage.
