Introduction
SpaceWire UK's IP is currently being adapted to have the industry standard AXI4 & AXI4-Stream interfaces and will be available inside a Xilinx Vivado IP Repository. The AXI4 interfaces will be used to control & monitor various aspects of the IP cores and the AXI4-Stream interfaces to transfer SpaceWire NCHARS and TIMECODES. Also in development is an embedded PetaLinux environment running on an ARM processor inside a Zynq FPGA that will host a Webserver and allow access to the IP cores register space via the Intranet & Internet.

AXI SpaceWire Packet Generator
The Packet Generator IP can be used to generate PACKETS on the AXI4-Stream Master (m00_axis) & TIMECODES on the AXI4-Stream Master (m01_axis) and receive PACKETS on the AXI4-Stream Slave (s00_axis) & TIMECODES on the AXI4-Stream Slave (s01_axis). The module is controlled via the AXI4 Slave (s_axi). The generated PACKETS have a header of [Packet Destination, Packet Generator Port] and are designed to travel from the Packet Generator, through a Switch, out on a physical SpaceWire link, back on physical SpaceWire link, through the Switch again, and ultimately returning to the Packet Generator.
