AUTOMATIC IMPLEMENTATION OF RADIATION PROTECTION ALGORITHMS IN PROGRAMS GENERATED BY GCC COMPILER

Radiation influence on the microprocessor-based sys-tems is a serious problem especially in places like acceler-ators and synchrotrons, where sophisticated digital devices operate closely to the radiation source. Reliability of such systems has significantly decreased due to effects like SEU or SEFI. One of the possible solutions to increase the ra-diation immunity of the microprocessor systems is a strict programming approach known as Software Implemented Hardware Fault Tolerance. SIHFT methods are based on the redundancy of the variables or procedures. Sophisti-cated algorithms are used to check the correctness of the control flow in the application. Unfortunately, a manual implementation of presented algorithms is difficult and can introduce additional problems with program functionality caused by human errors. Proposed solution is based on the modifications of the source code of the C language com-piler. Protection methods are applied at intermediate rep-resentation of the compiled source code. This approach makes it possible to use standard optimization algorithms during compilation. In addition, a responsibility for imple-menting fault tolerant is transferred to the compiler and is transparent for programmers
