Japan is developing a Japanese Experiment Module (JEM) constituting a part of the international space station. The Main Processing Controller (MPC) is a unit which is the center of the computer/network system of JEM. As authors have developed the development model of the MPC, they have introduced its overview in this paper. The MPC is one of the first computers for space applications with 32-bit processor architecture in Japan. It has far higher performance and far more memory capacity than computers equipped on ordinary satellites. This paper describes the major features of the development model of the MPC and its design considering restrictions as a space-borne component and environmental conditions in space, especially high-energy cosmic particle irradiation. Authors have manufactured and evaluated the development models and have obtained the results they had expected.
