SpaceWire-to-GigabitEther and SpaceWire backplane

In 2UU6, we developed SpaceWire platform named SpaceCube cooperation with JAXA and NEC. After the success of SpaceCube project, we developed number of SpaceWire products. Some examples of this innovation include several kind of the SpaceWire interface boards, SpaceWire router and SpaceCubeMK2. These developments included the support and cooperation of JAXA, OSAKA University, Japan Space Systems and NEC. In this paper we describe architecture, functions and usage about our new products which are the SpaceWire-to-GigabitEther and the SpaceWire backplane. The equipment used as verification for ASTRO-H of JAXA.
