Patent number: 4815030Abstract: A multitask multiuser system provides for efficient transfer of data from a remote data base to individual subscribers and has particular utility in the distribution of stock market data. A primary provider distributes the incoming data directly to user tasks or to an inquiry provider or a monitor provider. The inquiry provider responds to specific inquiries by users for information in the data base. The monitor provider maintains lists of information which are being monitored by the host computer for individual users. The inquiry provider and the monitor provider do not repeat requests to the remote data base where a similar request is already pending from another user. Data transfer paths between tasks are estabilished by a code module which may be linked to any of the tasks. The transfer paths are established using information from a configuration list and they are monitored by the operating system through a wait list established for each user task.Type: GrantFiled: September 3, 1986Date of Patent: March 21, 1989Assignee: Wang Laboratories, Inc.Inventors: Charley B.

Patent number: 4799187Abstract: Address generating apparatus for use in a computer system which includes a bus processor, a memory requiring 24-bit addresses, and a plurality of I/O processors, some of which generates 22-bit addresses and others of which generate 24-bit addresses on a system bus connecting them with the memory. The apparatus provides a 2-bit prefix to the address on the system bus when the address on the bus comes from a 22-bit device. The 22-bit devices are specified by a mask register and the prefixes by a set of prefix registers, one for each of the devices. When bus grant logic in the computer system determines which of the devices is to have control of the system bus, logic in the address generating apparatus determines from the mask register whether the device which is to receive control requires a prefix. If it does, the address generating apparatus outputs the device's prefix to the system bus's two most significant address lines at the same time as the device outputs a 22-bit address to the remaining address lines.Type: GrantFiled: July 30, 1987Date of Patent: January 17, 1989Assignee: Wang Laboratories, Inc.Inventors: Jeffrey W.
