To efficiently transfer large amounts of data and off-load the embedded processor, BitSim is offering its IP core, Bit-1G-UDP Ethernet.
This core offloads an embedded processor with the communication accelerated in the FPGA, with more than ~900+ Mb/s of effective data transfer rate. Standard functions for transmit, receive, ARP-handling, AXI-stream and loop back are included.
