Abstract
The invention relates to a circuit arrangement, comprising: a functional circuit with m (m=1, 2, . . . ) data inputs and n (n=1, 2, . . . ) data outputs for processing at least one m-dimensional binary data input (x, . . . , xm) to form an n-dimensional data output (y, . . . , yn), wherein the functional circuit comprises at least one combinatorial circuit part, at least two registers with a word length k (k=1, 2, . . . ; k≦n) which are coupled to at least some of the n data outputs of the functional circuit in order to store output values (y=y, . . . , yk; y'=y′, . . . , y′k) which are duplicated with respect to one another or are duplicated with bit-by-bit inversion with respect to one another, said output values being derived from the n-dimensional data output (y, . . . , yn) of the functional circuit, at least one corrector with an input word length 2k and an output word length k, which is coupled to data outputs of the at least two registers and supplies a k-dimensional corrected data output (y[k](korr)=y(korr), . . . , yk(korr)), and an error detection circuit for detecting errors during operation of at least one of the aforementioned circuit elements: the functional circuit, the at least two registers and the corrector.
