SHARING A PHYSICAL DEVICE AMONG MULTIPLE CLIENTS

摘要

A physical device has core function circuitry that is to perform a core I/O function of a computer system. Multiple client interface circuits are provided, each of which presents itself as a complete device to a software client in the system, to access the core function circuitry. Multiplexing circuitry couples the client interfaces to the core I/O functionality. Other embodiments are also described and claimed.
