Abstract: An incremental coder in which stable positions of the coder are defined by multiples of an increment of the coder. The coder computes a difference between a binary word obtained for a current stable position and a binary word obtained for a previous stable position, and computes the value of variation of stable positions by determining the integer part of the division of the difference by the number of increments between two stable positions.

Abstract: The invention relates to a method of managing data to be written several times into a memory organized in sectors, each sector requiring complete erasure to allow a new write operation in the sector. To secure the erasure of this type of memory, the method includes ordering the sectors of the memory and in reserving, for each sector, a header zone to receive a first word indicating that the latest erasure of the sector was carried out correctly, and a second word indicating that an erasure procedure for the preceding sector is in process.

Abstract: The invention relates to a method of managing data to be written several times into a memory organized in sectors, each sector requiring complete erasure to allow a new write operation in the sector. To manage the data in a revolving manner, the method includes: ordering the sectors of the memory, the sector ordering taking place in a revolving manner, the sector following the last sector being the first sector; reserving, for each sector, a header zone intended to receive a first word that defines the filling of the sector; defining, in each sector, locations each intended to receive a data item; and associating part of the header zone with each data location, the part of the header zone written when a data item is stored in the corresponding data location.
