Modular data processor construction - FACILITATES DEVELOPMENT, EXPANSION, AND MAINTENANCE USING INTERCONNECTED FRAMEWORKS WITH MODULES CONTG. FUNCTIONAL ELEMENTS

摘要

A modular data processing unit contains processing and control sections as well as stores and peripheral devices. The system functional elements have uniform connections and are connected together via ring circuits permitting optimum arrangement of modules each contg. one or more functional elements, and system extension by module insertion. Newly developed modules can be easily added and obsolete elements are easily replaced. Modules which are independent of each other are arranged in main frames in which all sockets are similarly wired. Modules for elements of different priority are inserted in a priority framework in which at least one terminal of each socket is connected with the non-corresp. terminal of the adjacent socket.
