Abstract: A universal packaging substrate, comprising a first substrate (102) and a silicon interposer (103), wherein, a plurality of bumps (106) are formed between the upper surface of the first substrate (102) and the lower surface of the silicon interposer (103) and electrically connect the upper surface of the first substrate (102) and the lower surface of the silicon interposer (103), and a plurality of wire bonding pads are formed on the upper surface of the silicon interposer (103) and are electrically connected to the bumps (106) respectively via silicon through holes (105). Also disclosed are a packaging structure provided with the packaging substrate and an packaging method. The substrate is suitable for small batch integrated circuit products, providing low cost and short cycle for packaging.

Abstract: The present invention relates to IP network communication technology. It provides a kind of IP multicast data layer distribution method and system. The method includes: first code original multicast data into multiple sub-flow, separately specify different shunt sub-source for every sub-flow, distribute sub-group address, create sub-group state, etc, form shunt structure. Then the sink send join news to each shunt sub-source, join each shunt sub-source sub-group and become the leaf node of each sub-tree. And then each shunt sub-source determine the intermediate node according to the port receiving join news and construct multicast distribution-tree. If the overlapping portion between the multicast distribution trees produce congestion, in the congestion nodes network coding is used to eliminate congestion and construct coding sub-tree according to the way of building multicast distribution tree from the below of the coding nodes.

Abstract: An optical disk drive system with quasi-parallel tasking comprises a decode/interface module, a servo control module and a procedure switch module. The decode/interface module receives and decodes at least one instruction to generate at least one corresponding procedure state. The servo control module generates at least one command according to the procedure state. The procedure switch module switches between the decode/interface module and the servo control module according to a received break signal. Furthermore, a servo control method is disclosed and comprises the following steps of: performing a decode/interface procedure for receiving and decoding at least one instruction to generate at least one corresponding procedure state; performing a servo control procedure for generating at least one command according to the procedure state; performing a break procedure for switching between the decode/interface procedure and the servo control procedure according to a received break signal.
