  • Patent number: 10891246
    Abstract: A buffer (32) for temporarily storing a packet is installed in a packet order control circuit (12H). A comparison circuit (31) compares the packet ID of an input packet with a next-selection ID indicating the packet ID of a packet to be selected next in accordance with an order. If the comparison result indicates that the packet ID and the next-selection ID do not match, a control circuit (36) stores the input packet in a storage position corresponding to the packet ID. If the packet ID and the next-selection ID match, the control circuit (36) selects the input packet as a target of a transfer process without storing the packet in the buffer (32). If the next-selection ID matches the packet ID of a packet stored in the buffer (32), the control circuit (36) selects the packet as a target of the transfer process. This guarantees the packet processing order with few memory resources.

  • Patent number: 10879272
    Abstract: A semiconductor device production system using a laser crystallization method is provided which can avoid forming grain boundaries in a channel formation region of a TFT, thereby preventing grain boundaries from lowering the mobility of the TFT greatly, from lowering ON current, and from increasing OFF current. Rectangular or stripe pattern depression and projection portions are formed on an insulating film. A semiconductor film is formed on the insulating film. The semiconductor film is irradiated with continuous wave laser light by running the laser light along the stripe pattern depression and projection portions of the insulating film or along the major or minor axis direction of the rectangle. Although continuous wave laser light is most preferred among laser light, it is also possible to use pulse oscillation laser light in irradiating the semiconductor film.
