Selective input / output board device and operation method by unifying input / output channel in main computer 3.2

摘要

The present invention provides a selective input / output processor which is a unified input / output channel that enables the connection of the SCSI / Besa module Eurocard bus, which is an input / output bus, through the unified selective input / output processor board of the main computer 3.2. The board relates to the input / output channels of the conventional main computer 3.1, which has two input / output channels including a system control module and an input / output processor, respectively. One unified one, including the SCSI / Besa module Eurocard controller, has a data buffer memory controller that integrates two input / output boards into one board while interfacing the two input / output buses. Designing an optional input / output processor board, an input / output board, simplifies manufacturing and design and provides economic benefits. The ensuite.
