Intellectual Property Cores
Xilinx offers IP cores for commonly used complex functions
including DSP, bus interfaces, processors, and processor
peripherals. Using Xilinx LogiCORE™ products and cores from
third party AllianceCORE participants, customers can shorten
development time, reduce design risk, and obtain superior
performance for their designs. Additionally, the CORE Generator™
system allows customers to implement IP cores into Virtex-5
FPGAs with predictable and repeatable performance. It offers a
simple user interface to generate parameter-based cores
optimized for our FPGAs.
The System Generator for DSP tool allows system architects to
quickly model and implement DSP functions using handcrafted IP
and features an interface to third-party system level DSP design
tools. System Generator for DSP implements many of the high-
performance DSP cores supporting Virtex-5 FPGAs including the
Xilinx Forward Error Correction Solution with Interleaver/
De-interleaver, Reed-Solomon encoder/decoders, and Viterbi
decoders. These are ideal for creating highly-flexible,
concatenated codecs to support the communications market.
Using Virtex-5 FPGA RocketIO transceivers, industry leading
connectivity and networking IP cores include leading-edge PCI
Express, Serial RapidIO, Fibre Channel, and 10 Gb Ethernet
cores can be implemented. The Xilinx SPI-4.2 IP core utilizes the
Virtex-5 FPGA ChipSync technology to implement dynamic phase
alignment for high-performance source-synchronous operation.
Xilinx also provides PCI cores for advanced system-synchronous
operation.
The MicroBlaze™ 32-bit processor core provides the industry's
fastest soft processing solution for building complex systems for
the networking, telecommunication, data communication,
embedded, and consumer markets. The MicroBlaze processor
features a RISC architecture with Harvard-style separate 32-bit
instruction and data buses running at full speed to execute
programs and access data from both on-chip and external
memory. A standard set of peripherals are also CoreConnect™
enabled to offer MicroBlaze designers compatibility and reuse.
All IP cores for Virtex-5 FPGAs are found on the Xilinx IP Center
Internet portal presenting the latest intellectual property cores and
reference designs using Smart Search for faster access.
Virtex-5 FPGA LogiCORE Endpoint Block Plus Wrapper
for PCI Express
This is the recommended wrapper to configure the integrated
Endpoint block for PCI Express delivered through the CORE
Generator system. It provides many ease-of-use features and
optimal configuration for Endpoint application simplifying the
design process and reducing the time-to-market. Access to the
core, including bitstream generation capability can be obtained
through registration at no extra charge.
