1.0 Product Highlights
The Ubicom IP2022 Internet Processor™ combines
support for communication physical layer, Internet
protocol stack, device-specific application, and device-
specific peripheral software modules in a single chip, and
is reconfigurable over the Internet. It can be programmed,
and reprogrammed, using pre-built software modules and
configuration tools to create true single-chip solutions for
a wide range of device-to-device and device-to-human
communication applications. High speed communication
interfaces
are
available
via
on-chip
hardware
Serializer/Deserializer (SerDes) blocks. These two full-
duplex blocks allow the IP2022 to be used in a variety of
communication bridging applications. Each SerDes block
is capable of supporting 10Base-T Ethernet (MAC and
PHY), USB, GPSI, SPI, or UART. The 120 MHz operating
frequency, with most instructions executing in a single
cycle, delivers the throughput needed for emerging
network connectivity applications, and a flash-based
program memory allows both in-system and runtime
reprogramming. The IP2022 implements most peripheral,
communications and control functions via software
modules (ipModule™ software), replacing traditional
hardware for maximum system design flexibility. This
approach allows rapid, inexpensive product design and,
when needed, quick and easy reconfiguration to
accommodate changes in market needs or industry
standards.
