2. The compression process as claimed in claim 1 , in which the executable code is divided into lines of a predefined number of instructions, each line of executable code being compressed into a line of parts of fixed length featuring in the block of parts of fixed length, and a line of parts of variable length featuring in the block of parts of variable length, each of the lines of parts of variable length being localized in the block of parts of variable length by means of the addressing table.

The compression process as claimed in claim 2 , in which the addressing table comprises one input per group of a predefined number of lines of parts of variable length, each input specifying the position of a first line of parts of variable length in the set of parts of variable length of the compressed code, and the respective lengths of the lines of parts of variable length of the group, except for a last line of parts of variable length of the group, whereof the length is determined by means of the position of a first line of parts of variable length of a following group of lines of parts of variable length.
