Abstract
Some of the biggest concerns in space systems are power consumption and reliability due to the limited power generated by the system's energy harvesters and the fact that once deployed, it is almost impossible to perform maintenance or repairs. Another consideration is that during deployment, the high exposure to electromagnetic radiation can cause single event damage effects including SEUs, SEFIs, SETs and others. In order to mitigate these problems inherent to the space environment, a system with dynamic and partial reconfiguration capabilities is proposed. This approach provide s the flexibility to reconfigure parts of the FPGA while still in operation, thus making the system more flexible, fault tolerant and less power-consuming. In this paper, several partial reconfiguration approaches are proposed and compared in terms of device occupation, power consumption, reconfiguration speed and size of memory footprints.
