Abstract
PURPOSE: To reduce the fixed-address area of a main memory by providing a common-use area into the memory of each module.
CONSTITUTION: Modules 2b and 2d, equipped with a priority logic circuit, receive and transmit data via bus 1 mutually. Then, respective memories 4 are incorporated in each module and contents of each module are written into common-use area 4a. This common-use area 4a is for transmission and reception of data to and from any other module via bus 1. In addition, each module is able to give a register reference instruction to common-use area 4a of any other module and also to read out data from module 2d reversely by setting results to common-use area 4a at the time of an insterruption from module 2d. Providing the common-use area like this eliminates the need of the conventional fixed-address area of the main memory.
