  • Method and means for enabling virtual addressing control by software users over a hardware page transfer control entity
    Patent number: 5377337
    Abstract: Provides a software-to-software interface and a software-to-hardware interface between software users and a hardware ADM facility (ADMF) in a data processing system. Such software user presents only virtual addresses to the software-to-software interface in a MSB list. The user list defines virtual address spaces, including a "hiperspace", in a manner that represents physical backing media as different random-access electronic storages, such main storage (MS) and expanded storage (ES). The real data transfers are within or between the backing storages. The user list is transformed into an ADM operation block (AOB), which is assigned an ADM UCB in a UCB queue which is associated with an ADM subchannel. The software-to-hardware interface generates an ORB, containing the AOB address, as an operand of a SSCB instruction which is executed to queue the associated subchannel onto one of plural co-processor queues in the ADMF.
