This thesis presents a platform for a small student satellite. A backplanesolution with slots for 8 individual modules is proposed. The backplane providesthe modules with power and a common data bus, as well as mechanismsfor isolating modules from the rest of the system and a possibility of restoringmisbehaving modules. It has a power consumption of about 100mW.An on-board controller has been designed and tested. It consists of a32-bit MCU, a NAND flash memory for housekeeping logs, an SRAM memoryfor processing variables, an OTP memory for safe storage of modulefirmwares, USB interface and a wireless intra-satellite communication module.The on-board controller has the main responsibility for monitoring andpreserving the satellite’s health. The power consumption will be dependentof the final firmware, but a rough estimate is about 100mW.Also, an experimental wireless intra-satellite communication system isproposed. The system consists of a small wireless module, that will be integratedonto any module that is a part of the wireless network.

With Moore’s law exponentially increasing the number of transistors on inte-grated circuits, developers fail to keep up. This makes chip area an increasinglycheap resource. At the same time, researchers and developers are trying to findways to dynamically reconfigure FPGAs, preferably at run time, so as to in-crease the flexibility of hardware solutions, and close the gap between the speedof hardware and flexibility of software. A proposed way of solving both of theseissues at once is by using nondeterministic finite-state machines as a fundamen-tal unit of design. This could provide great flexibility and dynamic hardwaresolutions, but before this can be known for sure, a system like this would needto be simulated. This paper documents the planning and development of a Sys-temC library that creates nondeterministic finite-state machines from regularexpressions, and a special regular expression syntax designed for this specificapplication. The paper can also be used as a reference for the inner workingsof, and how to use, the library.
