    Abstract: The present invention provides hardware logic within a host bridge 20 that connects a system bus 36 to a peripheral bus 22 using PCI bus architecture or a peripheral bus that uses a bus architecture similar to PCI. The inventive hardware optimizes the speed at which data transfers are accomplished between the buses while translating the data transfers between the different architectures of the two buses.

    Abstract: METHOD AND APPARATUS FOR PROVIDING BACK-TO-BACK DATA TRANSFERS IN AN INFORMATION HANDLING SYSTEM HAVING A MULTIPLEXED BUS A device for generating back-to-back data transfers on a bus in an information handling system is disclosed. The inventive device includes a detector for determining whether a first address value and a second address are within a range, a first register connected to the detector for storing the first address until the device generates the second address, a second register connected to the detector for storing the range value, and a transfer state block for driving the second address on the peripheral bus without a turnaround cycle if the detector determines that the first and second addresses are within the range. Thus, back-to-back data transfers are provided.
