| Outline of Final Research Achievements |
This research developed the on-board computer (OBC) which can evolve programs by making use of the bit inversion occurred by space radiation, and validates its effectiveness through both intensive computer simulations from the software viewpoint and the actual OBC from the hardware viewpoint. For this purpose, this research explored the evolutionary method that can evolve complex programs including the condition branch and the loop structure under the situation where the bit inversion is occurred not only in the commands but also in the registers in CPU. The intensive simulations and experiments have revealed that the proposed evolutionary method succeeded to evolve programs composed of the 33 commands of assembly language in PIC 10 developed by Microchip Technology Inc. This result increases the possibility of employing cheap, small, and fast CPU for many space applications.
