UDP/IP Cores

High Speed Ethernet Communication Cores

The UDP/IP Cores are suitable for implementing high-speed point-to-point communication with a PC when an UART or the parallel port is not fast enough.

It is highly suitable for sending large amount of data in one packet and in all-hardware or hw/sw solutions with demands for real-time performance.

RealFast is a member of the Common License Consortium. As a member, RealFast supports the SignOnce IP License for customers who wish to use any of our cores in Xilinx programmable logic devices. The SignOnce IP License represents a landmark accomplishment for the intellectual property (IP) industry. It is a set of standard terms being accepted by many of the industry's leading providers of soft IP cores for use in programmable logic. With this agreement, customers only have to review and execute one license to ease access to FPGA cores from multiple suppliers.
