Overview
|
Xilinx and its partners provide the building
blocks and expertise for many communications applications. The core
solutions and consulting services we provide help customers accelerate
time to market, keep pace with industry standards, and address the
industry's demands for high performance and low power solutions. Xilinx
FPGAs have been used to implement system level building blocks for
a variety of applications, including:
-
Wireless: spread spectrum, satellite modems, cellular/PCS base stations,
military radios and wireless local loop
-
Cable: modems, spectrum management and test equipment
-
xDSL technologies for high speed data over copper

Increased performance AND
programmability
|
| In the past, specialized DSPs have provided
designers a programmable solution, however these processors often failed
to deliver the performance required for high data rate applications. Xilinxâ
Virtex FPGAs and predesigned system level
building blocks achieve the parallel processing performance once realized
only with custom ICs. The solution is user programmable to deliver increased
flexibility at more attractive price points than can be achieved with DSPs. |
Put more digital into
wireless signal processing
|
| Configurable hardware digital processing solutions
can be deployed closer to antenna systems thereby eliminating analog components.
Virtex FPGAs can process incoming data at
frequencies in the RF (radio frequencies) and IF (intermediate) frequency
range with data sample rates well above 100 MHz. |
Faster deployment of Internet channels
|
| FPGAs are capable of integrating
complete high speed, high bandwidth communications channels for xDSL, Internet
over cable, and wireless networks. The solutions inherent programmability
allows system operators to test and verify innovative algorithms in real
time öover a real communications channel. Schedule delays typically
incurred by the need to develop real time software for multiple DSP processors
can be avoided entirely. |
FPGAs at work in wireless base stations
|
Xilinx FPGAs are used in both PCS and
cellular wireless base stations to implement complex functions requiring
performance beyond the capability of a specialty processors, such
as: channelization, filter matching, sequence generation, modulation,
error control, and encryption. Xilinx and its partners provide solutions
for basic building blocks and high level functions to help you accelerate
your deployment of fully programmable base stations to meet multiple
voice and data standards. Features of the solutions include:
-
FPGAs connect directly to high-speed A/D converters
and process the data through to base-band rates where DSP processors take
over.
-
Fully programmable base stations permit the transition
to next generation standards while maintaining support for existing standards.
-
PCI and Compact PCI bus cores (33 and 66 MHz) to provide the backbone for
integrating board level building blocks.

Satellite modems simplified
|
| Most satcom systems require data rates that
exceed the capabilities of DSPs. As a result, FPGAs have become a popular
alternative. Designers of satellite base station equipment take advantage
of FPGA to implement high performance system building blocks including
filtering, modulation and error control. In doing so, they successfully
simplify development and avoid the cost and schedule delays associated
with custom IC design. |

Reconfigurable Radio
|
Programmable RF/IF blocks are key
to implementing a fully programmable communications infrastructure. FPGAs
implement hardware solutions defined by a digital bit stream. By simply
reconfiguring the FPGA you can support emerging standards, deploy system
upgrades, reallocate channels, or perform system maintenance.
In addition, fully programmable solutions built
with FPGA and DSP processors can be upgraded by sending commands over a
network. Xilinx' Internet reconfigurable logic (IRL) technology promises
to help make reconfiguration ultimately easy. |
