LogiCORE Products

LogiCORE products are sold, licensed and supported by Xilinx. They are developed internally by Xilinx or jointly with a partner.

The cores that Xilinx provides as LogiCORE products typically fall into one of two categories. The first are high-performance interface cores that require a thorough understanding and control of the FPGA technology and implementation software in order to achieve the desired performance and complexity. An example of a core in this category is the LogiCORE PCI interface.

The second category are cores that benefit from a very specialized implementation in the FPGA. An example is the LogiCORE DSP modules that are implemented using a unique algorithm, Distributed Arithmetic. This algorithm fits the lookup-table-based architecture of the FPGA. The result is outstanding performance and device utilization, often more than 10 times better than generic HDL descriptions.

Xilinx CORE Generator

In addition to actual cores, Xilinx is committed to develop enabling design tools and methodologies to facilitate usage of cores with FPGAs. The first of this product type is the CORE Generator tool. This innovative methodology for acquiring and using cores allow to combine the benefits of 1) a firm core with predictable performance, and 2) the flexibility of system level design, facilitated by behavioral description languages such as VHDL and Verilog.

LogiCORE products are customized to fit your specific application using an intuitive graphical user interface. Based on your inputs, the CORE Generator generates a proven core with predictable timing that can be integrated using a VHDL-, Verilog- or schematic-based design flow. As a result, you can put several, individually proven cores with given performance, into one system on a single FPGA. Because each core is already verified, the time-to-market benefits are maintained for high-complexity FPGAs.

Xilinx PCI Solutions

The Xilinx PCI solution includes the necessary devices, tools and cores to build a cost-effective single-chip PCI system in record time.

  • LogiCORE PCI - the highest performing PCI core with predictable timing
  • XC4000E/XLT - the industry's fastest FPGAs that allow you to integrate a PCI interface plus 5 to 60 thousand gates
  • Spartan - the industry's lowest cost FPGA; on-chip RAM allows high performance for the most cost-effective programmable solution for PCI.
  • HardWire - an automatic migration path to a low-cost chip for volume production
  • Web-based configuration - for easy configuration and integration of the LogiCORE PCI module
  • 3rd party Design Centers - with PCI expertise available for special applications and customization of the core
PCI is an extremely high-performance and complex specification that is challenging to meet in any technology. To meet the stringent PCI specification the core is carefully hand-tuned for the targeted architecture. Placement and routing for the critical parts of the core are locked down to ensure that timing can be met every time the core are implemented.

To achieve our goals, the LogiCORE development team is working closely with both IC and Software teams. New methodologies for characterizing and modeling our FPGAs have been developed as a result of this teamwork. You will have access to state of the art technology and expertise, allowing you to complete your PCI application in record time.

Xilinx has sold hundreds of LogiCORE PCI licenses and has built up a solid knowledge about PCI. We are committed, and will continuously improve our PCI products to remain state of the art.

Xilinx DSP Solutions

Using an FPGA to implement DSP functions often allow a radical performance advantage over fixed processors while maintaining maximum flexibility and shortest time-to-market. Until now, tools to automate the design process have been lacking and most designs have been completed manually by experienced FPGA designers.

Xilinx' DSP LogiCORE products are complex parameterized DSP building blocks that deliver performance and density equal to or better then a hand-tuned implementation. LogiCORE DSP modules can be used with VHDL, Verilog or schematic capture design methodologies.

Higher level DSP cores are available from our AllianceCORE partners.

Acquiring LogiCORE Products

LogiCORE products are available from your local Xilinx sales representative similar to other Xilinx software products. Xilinx and your local sales representative will also be your primary source for support of the core, the devices and the design tools. You can also send email questions to: logicore@xilinx.com.
