PROVIDING INDIRECT DATA ADDRESSING IN INPUT/OUTPUT PROCESSING SYSTEM WHERE INDIRECT DATA ADDRESS LIST IS FRAGMENTED

摘要

FIELD: information technology.;SUBSTANCE: method involves receiving a control word for an input/output operation. The control word includes an indirect address for data associated with the input/output operation. The indirect data address includes a starting address of a list of storage addresses that collectively describe the data, the list containing two or more discontiguous storage addresses. Data is gathered in accordance with the list. The gathered data are transmitted to a control device in an input/output processing system.;EFFECT: high throughput of data exchange owing to less handshaking.;10 cl, 11 dwg
