Resumen
The invention describes a method for the detection and correction of multiple errors in the data stored in the volatile memory of an electronic system, such as those caused by cosmic radiation in aerospace systems, based on a pyramidal encoding/decoding through the so-called seed bits. Hsb that are soldered or physically fixed on the printed circuit board. The coding phase groups the selected memory bits in blocks equally, calculates the detection and correction check words for each block, and calculates and physically fixes the seed bits hsb. The decoding phase periodically calculates the detection and correction check words of each block in two duplicate functions, detects and corrects errors in these check words from the hsb seed bits set in coding, and detects and corrects errors in the data stored in memory.
