How many legacy PCs become useless
simply because they lack up-to-date I/O
connectivity? Sometimes all it takes to
bring new life to an old PC is to add
USB 2.0, Firewire or Ethernet
connectivity. This is easily accomplished
with a PCI Combo Card. A single add-
in card can have several I/O devices; but
they all
can’t
connect directly to the system PCI bus,
so some kind of bridge is required. A
classic example is the USB
2.0/Firewire/Ethernet combo card shown
here. These low-end PCs and their add-
in cards are usually quite cost-sensitive,
and the standard PCI-to-PCI Bridge
from Intel adds too much to the BOM cost.
The Solution: Low-Cost Load Expansion with the
PCI 6140
On these PCI combo cards, there are normally two to four PCI devices
behind the bridge on the card. These PCI devices include USB, Firewire,
and Ethernet I/O chips as in this example; other combo cards include
RS 232, MIDI, SPDIF, TV Tuners, MPEG Decoders and Encoders,
Audio Processors, and other multimedia devices. The PCI Specification
allows each PCI slot only one device load. In order for multiple devices
to reside on the card, the PCI 6140 provides the lowest-cost isolated PCI
bus on its secondary. This bus can handle up to four PCI devices at
33MHz.

Is There Enough Bandwidth with 32-
bits/33MHz PCI?
The 32-bit, 33MHz PCI bus allows a maximum
throughput of 125MB/s, (or 1000Mb/s). Compare
this with the maximum rates for USB 2.0 (480Mb/s),
Firewire (400Mb/s) or 10/100 Ethernet (100 Mb/s).
You can see there is plenty of bandwidth for the
devices behind a 32-bit bridge like the PCI 6140.
