MOST (Media Oriented System Transport)
is creeping into high-end autos to
deliver high-performance multimedia
to passengers. The MOST150 standard
pushes bandwidth to 150
Mbits/s and adds an IP channel to the
mix that can carry Ethernet 100BaseT
traffic. It also doubles the MOST
bandwidth to 50 Mbits/s compared
to MOST25 (see figure).
MOST addresses fixed-bandwidth
applications such as streaming audio
and video. Though MOST is slower
than the Ethernet channel, its quality
of service (QoS) is guaranteed. The
addition of an Ethernet channel allows
a single MOST Polymer Optical Fiber
(POF) network to support wired and
wireless peripherals attached to the
network. IP-based Ethernet traffic is
independent and cannot interfere with
the MOST channels.
The OS81110 INIC incorporates
SMSC's Cougar microcontroller to provide
a more intelligent MOST controller.
Pricing for the OS81110 INIC is
less than $5.
