Abstract: A method for determining r error detection bits that can be associated with a word of m bits to be coded, including the step of calculating the product of a vector with m components representative of the word of m bits to be coded and of a parity control matrix of dimension r×m. The parity control matrix is such that each column of matrix includes an odd number of “1s” greater than or equal to three. The present invention also relates to a method for determining a syndrome.

Abstract: A method for securing a memory area comprising data blocks, wherein at least two control bits are associated with each data block, is provided. The method comprises a step of reading the control bits associated with a current data block intended to be replaced with the new data block, before the writing of a new data block in the memory area. A securing action for securing the memory area is begun if the two control bits have the same value. Upon each write of a new data block in the memory area, control bits having opposite values are written in the memory area. The method may be applied, for example, to the securization of a binary counter.

Abstract: A method for detecting a malfunction in a state machine is described. The state machine has an operation modeled by a set of states linked to each other by transitions, the state machine generating, upon each transition, output signals according to input signals comprising signals generated during a previous transition. During a transition, the method comprises steps of generating at least one control signal according to a control signal generated during a previous transition, determining an expected value of the control signal, and comparing the control signal with the expected value.

Abstract: A matrix H for encoding data words is defined for wide word ECC with uniform density and a reduced number of components. The H-matrix is incorporated in an encode unit operable to Hamming encode a data word with a 10×528 matrix generated in groups of four columns wherein; a first column is a complement of a second column; the value of the second column ranges from 9 to 271 in increments of two; a third column is a complement of a fourth column; and the value of the fourth column is the same as the value of the second column less one; and wherein a 528-bit bottom row is added to the 10×528 matrix comprising alternating zeroes and ones starting with a zero creating an 11×528 matrix.
