Abstract

In an IBM PC AT-compatible computer architecture, CPU-generated addresses and data for accesses to a peripheral device in the I/O address space are coupled directly to the peripheral device from the local bus, without traversing the I/O bus. Any data returned from the peripheral device is coupled directly to the local bus, also without traversing the I/O bus. No buffers are needed for communicating such address and data information between the peripheral device and the I/O bus.
