DEVICE FOR SELECTING BOARD OF COMMUNICATION MODULE

摘要

PURPOSE: A device for selecting a board of a communication module is provided to compare addresses by using the board ID information when a high level processor accesses a memory of a low level processor on one module formed with processor boards for a communication system. CONSTITUTION: The high level processor(MP) generates a VME(Versa Module Europe) address for selecting the low level processors(SP1-SPn). The low level processor comprises a tool converting the board ID information set to a backboard and the tool generating a match signal when a local address and the VME address are same. The data of an address area in the low level processors is accessed by selection of the high level processor.
