ABSTRACT:
An integrated processor that employs a bus interface unit to accommodate high performance data transfers via an external peripheral interconnect bus with multiplexed address/data lines. The peripheral interconnect bus, which may be a PCI standard bus, accommodates data transfers between an internal bus of the integrated processor and PCI peripheral devices. The integrated processor further includes a sub-bus control unit that generates a set of side-band control signals that allow the external derivation of a lower performance secondary bus, such as an ISA bus, without requiring a complete set of external pins for the secondary bus on the integrated processor. The derivation of the secondary bus is accomplished with an external data buffer and an external address latch which are controlled by the side-band control signals. Separate address and data lines from the integrated processor for the secondary bus are not required. Accordingly, high performance peripheral devices are supported by the integrated processor as well as lower performance, lower-cost peripherals without a significant increase in the pin-count of the integrated processor. Accordingly, overall cost of the integrated processor is kept low while a wide range of peripheral devices are supported.
