Abstract :
In this paper we propose a mitigation technique for the protection of critical data in electronic devices from Single Error Upsets (SEU) that manifest themselves as bit-flips in memory. In order to cope with this problem, we take advantage of convolutional codes. We propose a methodology to generate a light decoder architecture considering all the possible combinations of generator polynomials of order three. The automatic generation of VHDL code is also addressed by exploiting a framework for cores generation. The comparison with other protection schemes shows that the approach is advantageous in terms of performance and error coverage.
