Abstract : The objective of this paper is to propose a low-cost, robust Error Detection And Correction EDAC solution for use in applications such as nano satellites, where price is a primary concern. Different methods have been evaluated, with the main result mitigation Single Event Effects causing bit-flips in system memory utilizing Bose-Chaudhuri-Hocquenghem BCH codes. The general implementation is resource intensive and the algorithm has been adapted to the embedded platform. The codes have been implemented on a low-cost microcontroller with a real time operating system and faults have been injected during run-time to emulate a radiation environment. The performance impact and dynamic behavior of the algorithms is studied with third party trace analysis tools.
