ABSTRACT:
A computer system in which a host bus is relieved from the burdens of data transfers between main memory and devices connected to an input/output (I/O) bus. Instead, the invention operates to place most of the burden of the data transfer on an internal bus within a bus arbitration unit so that the host bus is freed up much sooner than conventionally achieved. As a result, the computer system has substantially better performance because the host bus is available for other processing operations instead of being tied up with data transfers with devices (e.g., peripheral devices) connected to the I/O bus.
