Document Type and Number:
WIPO Patent Application WO/1992/006057
Kind Code:
A1
Abstract:
A system for controlling the issues of input/output instructions applicable to a data processing system which includes a processor module having a CPU and adaptor modules which are in connection with the processor module by a system bus and control input/output devices according to the input/output instructions issued from the processor module. While the CPU executes other instructions after issuing the input/output instructions, the adaptor modules execute the input/output instructions and transfer the results of processing to the processor module. When the results sent from the adaptor modules are not normal, the CPU receives interrupt requests to provide the results of processing in the adaptor modules.
