 *               cpu_pos     : Current positions in the cpu_buffer 
 *               cpu_size    : The memory size of the cpu_buffer

 *                             pentinum-mmx so on, use this flag to specify which type

 *                             other or any sub model.

 * Return value :

 *               value  0            : wrong opcode or not vaild opcode
 *               value +1 and higher : who many byte we should add to cpu_pos
