Abstract

This paper presents a prototype of a hardened version of the 8051 micro-controller, able to assure reliable operation in the presence of bit flips caused by radiation. Aiming at avoiding such faults in the 8051 micro-controller, Hamming code protection was used in its SRAM memory and registers. This paper shows implementation details of this technique in the micro-controller VHDL description and the impact on the device area.
