Method and system for handling data values and structure in a memory

A method to retrieve data values and data structure from a memory of an embedded system, the memory also storing executable code uploaded to the embedded system by an external system through a firmware, the method comprising:

• reading at a deserializer, from the memory, successively a total size Stot on first R bytes, R being a predetermined number of bytes, and a series of bytes on next (Stot−R) bytes;
• deconcatenating by the deserializer the series of bytes into successively a size, Si, of a data, Di, the size Si corresponding to a number of chunks, Dij, forming the data Di, with j ranging from 1 to Si, and values of the chunks Dij for the data Di, with i ranging from 1 to a maximum number of data;
• and
• sending by the deserializer to the executable code, the size Si of each data Di, and for each data Di, the values for each of the chunks Dij forming the data Di, with j ranging from 1 to Si, for all i respectively.

A system to store and retrieve data values and data structure in a memory of an embedded system, the memory also storing executable code uploaded to the embedded system by an external system through a firmware, the system comprising:

• a serializer configured to:
• receive from the executable code, with i ranging from 1 to a first maximum number of data:
• the size, Si, of a data, Di, the size Si corresponding to a number of chunks, Dij, forming the data Di, with j ranging from 1 to Si;
• and
• for each data Di, the value for each of the chunks Dij;
• form a first series of bytes, obtained through concatenation of successively Si and Dij, with j ranging from 1 to Si, for i ranging from 1 to the first maximum number of data;
• and
• write to the memory, successively a total size Stot on R bytes, R being a predetermined number of bytes, and the formed first series of bytes;
• and
• a deserializer configured to:
• read from the memory, successively a total size S′tot on first R bytes, and a second series of bytes on next (S′tot−R) bytes;
• deconcatenate the second series of bytes into successively a size, S′i, of a data, D′i, the size S′i corresponding to a number of chunks, D′ij, forming the data D′i, with j ranging from 1 to S′i, and values of the chunks D′ij for the data D′i, with i ranging from 1 to a second maximum number of data;
• and
• send to the executable code, the size S′i of each data D′i, and for each data D′i, the values for each of the chunks D′ij forming the data D′i, with j ranging from 1 to S′i, for all i respectively;
• the system being further configured to calculate the total size, Stot, as the sum of bytes in the formed first series of bytes, plus R bytes.
