 * Millisec.c
 * Millisec module
 *
 * The millisec task is called once every 1 millisecond to gather data from the FPGA crucial modules,
 * so it will be ready for the Millisec operations. it is called 300 (TBD, configurable)
 * microsecond before the Millisec task, so that the data will be ready for the Millisec handling.
 * the ,millisecond task holds the pointer to a double buffer of results, so that the Millisec will handle the
 * most updated data, without disturbing data gathering
