| Zusammenfassung: | A data processing system includes a processor core, a system memory coupled to the processor core, an input/output adapter (IOA), and an input/output (I/O) host bridge coupled to the processor core and to the IOA. The I/O host bridge includes a register coupled to receive I/O messages from the processor core, a buffer coupled to receive I/O messages from the IOA, and logic coupled to the register and to the buffer that services I/O messages received from the register and from the buffer. |
