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, our
CORE Generator™ system allows customers to implement
IP cores into Virtex-4 FPGAs with predictable and repeat-
able performance. It offers a simple user interface to gener-
ate parameter-based cores optimized for our FPGAs.
The System Generator for DSP tool allows system archi-
tects to quickly model and implement DSP functions using
handcrafted IP, and features an interface to third-party sys-
tem level DSP design tools. System Generator for DSP
implements many of the high-performance DSP cores sup-
porting Virtex-4 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.
Industry leading connectivity and networking IP cores
include the electronics industry's first Advanced Switching
product, leading-edge PCI Express, Serial RapidIO, Fibre
Channel, and 10Gb Ethernet cores that include Virtex-4
FPGA RocketIO multi-gigabit serial interfaces. The Xilinx
SPI-4.2 IP core utilizes the Virtex-4 FPGA embedded
ChipSync technology to implement dynamic phase align-
ment for high-performance source-synchronous operation.
MicroBlaze™ processor 32-bit core provides the industry's
fastest soft processing solution for building complex sys-
tems for the networking, telecommunication, data communi-
cation, embedded and consumer markets. The MicroBlaze
processor features a RISC architecture with Harvard-style
separate 32-bit instruction and data busses 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 pro-
cessor designers compatibility and reuse.
All IP cores for Virtex-4 FPGAs are found on the Xilinx IP
Center Internet portal presenting the latest intellectual prop-
erty cores and reference designs via Smart Search for
faster access.
