VIRTUAL PERIPHERAL COMPONENT INTERCONNECT MULTIPLE-FUNCTION DEVICE

摘要

A peripheral component interconnect (PCI) device (200) comprising a bus interface (216) coupled to a component interconnect bus (102), a plurality o f configuration space register sets (206A-N), and virtual multiple-function logic (204). Each set of configuration space registers (206A-N) is associate d with a function. The virtual multiple-function logic (204) is coupled to the bus interface (216) and the configuration space register sets (206A-N). The virtual multiple-function logic (204) provides access to a plurality of configuration space registers (206A-N) for a plurality of functions. The virtual multiple-function logic (204) also enables a plurality of functions to share the bus interface (216) and other internal logic.
