Abstract: PO987-007 DOMAIN RELATED ACCESS LISTS A method and apparatus is provided to translate the contents of access registers into information for use in performing addressing functions for multiple virtual address spaces. The access registers represent the full addressing capability of the system but do not directly contain the addressing information. The system has a plurality of general purpose registers, a plurality of access registers associated with the general registers, an access list having access list entries which is addressed by the contents of the access register, memory storage for holding address space number second table entries (ASTE), where the contents of the access list entry locate the ASTE and where the ASTE contains the addressing information needed to locate a virtual address when combined with the contents of a general register, Access register translation (ART) consists of the process of determining addressing information by using the access list entry and the ASTE. The system has available to it at any one time a selection of one of two domains each represented by an access list. One domain is related to the dispatchable unit task to be performed and the other is related to the address space in which a particular program operates. The ART process selects the domain which the access register is using.

Abstract: A user through a personal computer, in real time, controls the activation and selection of voice and data transmission paths in a communication network independent of network profiles. The network includes a public switched telephone network and a data network, e.g. the Internet for voice and/or data transmissions over either the voice or data networks. In the network, a voice terminal and a computer terminal are coupled to a shared voice and data terminal. A digital subscriber line access multiplexer is coupled to the shared voice and data terminal; the data network through a client server interface, and a voice network through an intelligent switch. The client server interface includes programmable stored data descriptive of network-authorized data and voice functions and transmission paths in the voice and data networks. The interface is linked to the multiplexer and switch for transmitting signaling messages directing traffic to the voice and data networks in accordance with the stored data. The computer terminal displays menus obtained from the client server which enable the user, in real time, to activate and select voice and/or data transmission paths through either the voice and/or data networks independent of pre-defined network profiles and/or traditional traffic assumptions.

Abstract: P0984011 LINKAGE MECHANISM FOR PROGRAM ISOLATION A computer system has general purpose registers, control registers and access registers for containing information to allow address space capability. A linkage stack uses protected address space to store state information during program call and program return operations. The linkage stack contains information relating to state entries for the saved information and header and trailer entries to point to other linkage stack sections. A control register contains the pointer to the current linkage stack entry and is changed as the program call or return moves through the stack.

Abstract: PO9-87-006 NONHIERARCHICAL PROGRAM AUTHORIZATION MECHANISM A program authorization mechanism for authorizing access to an address space in the main memory of a computer system by a program being run under a multiple address space facility. An access-list entry is associated with each address space, each access-list entry being designated by an access list-entry token contained in an access register. Each access-list entry includes a private indicator which indicates if the associated address space can be accessed by all programs from this access-list entry or if the associated address space can only be accessed by an authorized program. For a program to be authorized, an extended authorization index in a control register must match an access-list extended authorization index in the access-list entry, or the extended authorization index value must be authorized in an authority table associated with the address space. An instruction for testing a given extended authorization index for a given access-list-entry is also disclosed.

Abstract: PO98/-004 ACCESS REGISTER TRANSLATION MEANS FOR ADDRESS GENERATING MECHANISM FOR MULTIPLE VIRTUAL SPACES A method and apparatus is provided to translate the contents of access registers into information for use in performing addressing functions for multiple virtual address spaces. The access registers represent the full addressing capability of the system but do not directly contain the addressing information. The system has a plurality of general purpose registers, a plurality of access registers associated with the general registers, an access list having access list entries which is addressed by the contents of the access register, memory storage for holding address space number second table entries (ASTE), where the contents of the access list entry locate the ASTE and where the ASTE contains the addressing information needed to translate a virtual address when combined with the contents of a general purpose register. Access register translation (ART) consists of the process of determining addressing information by using the access list entry and the ASTE. The results of the ART process are stored in an ART lookaside buffer (ALB) which stores the results of ART while valid for later use.
