PCI express performance

The ExpressLane™ PEX 8311 1-lane PCI Express (PCIe) to 32-bit, 66MHz generic local bus bridge offers complete protocol translations between these two standards.

multiple configuration options

You can configure the FPGA using the Xilinx Platform Cable (JTAG), using your own UDK-based software, using the UDK3 board manager or from the on-board flash memory. All this options are always available - there is no need to choose with switches or jumpers.

PIB slot for users peripheral

The PCIVe4BASE FPGA board comes with the slot-board "PIB64IO" as default. It has 8 5-Volt tolerant buffers with 8 signals each. The buffer directions are switchable by FPGA io signals. For special requirements, you can develop your own custom PIB or ask to get an offer.

free useful tools

Included in the UDK, there are tools to perform FPGA configuration, send and receive data and control the reset-pin. 

Unified Development Kit UDK and API

The Cesys UDK is an API for FPGA configuration and interfacing the FPGA to the software running on your PC. The UDK handles everything between a API call from your software and a Wishbone bus transaction inside the FPGA. Read and write calls are serialized through the PCIe interface, making the FPGA bus address space directly accessible by your software. Using the UDK results in an enormous saving in time and development resources. It is available at no additional cost when used with Cesys boards. To use it with 3rd party hardware, we offer a pay-once licensing model for the UDK source-code.

reference design

Use our extensively tested reference designs as a starting point for your projects. We use our own reference designs for many customer projects and can therefore offer you the very best support.

design-in support

We have great interest in ensuring that your project is successful. That is why we will give great effort to assist you. We will answer questions that you ask in our support-forum as soon as possible because sometimes, it's the little things that stop you. In addition to our free forum-support, we offer fee-based support and development service customized to your needs.

prototyping and OEM integration

The PCIeV4BASE was built for prototyping systems and integration into OEM devices.
