The Home Wirechip set unleashes the power of net-
working in the home by enabling a host of applications,
allowing users to maximize their investment in periph-
eral devices, and take full advantage of existing narrow-
band or future broadband connections. The Home Wire
chip set supports multimedia and real-time applications
using priority-based queuing to ensure quality of ser-
vice (QoS), enabling such applications as voice and
video over IP in the home. The Home Wirechip set pro-
vides the core technology for the following:
I
Internet connection sharing
I
Peripheral sharing (i.e., printers, scanners, etc.)
I
File and application sharing
I
Entertainment (i.e., multiplayer gaming)
I
Home automation
I
IP telephony
I
Video over IP
I
PC-to-PC intercom
I
Residential gateways
The HW3100/HW2000 Home Wirechip set also has
provisions to support either a line codec or silicon DAA
enabling the use of V.90/V.92 host-controlled modem
technology.
V.90/V.92 host-controlled modem technology has been
enabled by the availability of ample processing power
in today’s PCs. V.90/V.92 host-controlled modem tech-
nology eliminates the need for a dedicated digital signal
processor to perform the specialized telephone line sig-
nal processing functions; the host processor assumes
this function.
With the Home Wirechip set, V.90/V.92 modem func-
tionality can be easily added to the design, eliminating
the need for a separate PCI-based modem. A precious
PCI slot is also freed up and the overall system cost is
significantly reduced. In addition, the use of a silicon
DAA with the Home Wirechip set reduces the overall
cost, since a significant number of discrete compo-
nents can be eliminated.
The Home Wirechip set is also compliant with the
PC99 specification and the PCI Bus Power Manage-
ment Interface Specification.
