The SpaceWire IP core is compliant with the IEEE 1355 standard. It is capable of 100Mbps full duplex bitrate. Support for FreeRTOS, RTEMS and Linux is available, a TCP/IP networking driver is provided for Linux. This IP core comes in 2 different versions. The first one is presented to the processor as a peripheral (AXI/AHB), the second one is a "bare metal" implementation that can be connected to any HDL design without any processor involved or when maximum bitrate is needed.
