NEC and JAXA performed evaluation of SpaceWire-R IP Core (in VHDL) as a part of JAXA Standardization activities in Japanese fiscal year 2014 (April 2014 - March 2015). Results of the performance evaluation project will be presented including packet transmission latency and throughput for various payload lengths, segmentation size, and the number of concurrently opened communication channels. Since the protocol specification has been slightly updated to remove complexity in the last few months, we will also describe changes made to the specification.
