1. the management method of shared drive in the multiple nucleus system is characterized in that, comprising:

  • Based on the miscellaneous service length of data package in the multiple nucleus system;

    Internal memory that the overall situation of configuration all lengths type is shared in multiple nucleus system and the local internal memory of sharing;

    All central processing units CPU in the multiple nucleus system can both visit the internal memory that the said overall situation is shared, and the portion C PU in the multiple nucleus system can visit the internal memory that share said part;

    The internal memory that CPU in the said multiple nucleus system shares through the said overall situation comes beared information with the local internal memory of sharing;

    When the internal memory that exists polytype said global sharing memory and/or said part to share in the multiple nucleus system can carry with a kind of business data packet, the free memory block in the internal memory that share the said global sharing memory of the type that selection length is minimum and/or said part carried said business data packet;

    Transmit between each CPU of interior existence that the overall situation of carrying said business data packet is shared, the internal memory said overall situation is shared by the CPU of the shared internal memory of the said overall situation of last use discharges.
