ABSTRACT:
The assembly comprises a circuit for detecting errors in data supplied by at least one of the blocks of the assembly. When an error has been detected, the assembly is decontaminated by one circuit for backup and reconstitution of past states of a latch associated to a block. The backup and reconstitution circuit comprises a multiplexer and buffer register. The multiplexer comprises a first input directly connected to the output of the latch and a second input connected to this output via the buffer register. A control circuit controls the buffer register and the multiplexer so as to activate the buffer register writing function and connect the output of the multiplexer to its first input at each cycle, during a normal operation phase, and to read enable the buffer register and connect the multiplexer output to its second input during predetermined cycles of a decontamination phase.
