Local bus interface for controlling information transfers between units in a central subsystem |
摘要 |
In a data processing system, a central subsystem includes a plurality of special purpose processing units with one of the processing units serving as a control processing unit within a central subsystem. The processing units are coupled to a common subsystem bus for the transfer of data, control information, and address information within the central subsystem. Access to the subsystem bus is allocated by a bus control unit which also interfaces the central subsystem with other processing units such as a system memory or system I/O devices that are included in the data processing system.
