BIDIRECTIONAL DATA STORAGE FACILITY FOR BUS INTERFACE UNIT

BIDIRECTIONAL DATA STORAGE FACILITY FOR BUS INTERFACE UNIT

A METHOD AND SYSTEM ARE PROVIDED FOR CONTROLLING DATA TRANSFER BETWEEN A SYSTEM MEMORY (24,26) CONNECTED TO A SYSTEM BUS (76) AND AT LEAST ONE INPUT/OUTPUT (I/O) DEVICE (28) CONNECTED TO AN I/O BUS (32) IN A COMPUTER SYSTEM (10). THE SYSTEM BUS IS COUPLED TO THE I/O BUS BY A BUS INTERFACE UNIT (64)...

description A METHOD AND SYSTEM ARE PROVIDED FOR CONTROLLING DATA TRANSFER BETWEEN A SYSTEM MEMORY (24,26) CONNECTED TO A SYSTEM BUS (76) AND AT LEAST ONE INPUT/OUTPUT (I/O) DEVICE (28) CONNECTED TO AN I/O BUS (32) IN A COMPUTER SYSTEM (10). THE SYSTEM BUS IS COUPLED TO THE I/O BUS BY A BUS INTERFACE UNIT (64) COMPRISING A FIRST PAIR OF BUFFERS (125A, 125C) CONNECTED IN SERIES BETWEEN THE I/O BUS AND THE SYSTEM BUS, AND A SECOND PAIL OF BUFFERS (125B, 125D) CONNECTED IN SERIES BETWEEN THE I/O BUS AND THE SYSTEM BUS AND IN PARALLEL WITH THE FIRST PAIR OF BUFFERS. EACH OF THE BUFFERS IN EACH OF THE PAIRS IS USED FOR BIDIRECTIONAL DATA TRANSFER BETWEEN THE SYSTEM BUS AND THE I/O BUS. FIG.1
