A Very Long Instruction Word (VLIW) processor having an instruction set with a reduced size resulting in a small number of bits being necessary to specify registers. The VLIW processor includes a register file, and first through third operation units, and executes a very long instruction word. Further, the very long instruction word includes a register specifying field which specifies a least one of the registers in the register file and a plurality of instructions. The operand of each instruction includes bits src1, src2, and dst, which indicate whether or not the registers specified by the register specifying field are to be used as the source register and the destination register.

A processor according to the present invention includes a decoding unit 20, an operation unit 40 and others. When the decoding unit 20 decodes Instruction vcchk, the operation unit 40 and the like judges whether vector condition flags VC0˜VC3 (110) of a condition flag register (CFR) 32 are all zero or not, and (i) sets condition flags C4 and C5 of the condition flag register (CFR) 32 to 1 and 0, respectively, when all of the vector condition flags VC0˜VC3 are zero, and (ii) sets the condition flags C4 and C5 to 0 and 1, respectively, when not all the vector condition flags are zero. Then, the vector condition flags VC0˜VC3 are stored in the condition flags C0˜C3.

An object of the present invention is to provide a decoding circuit, a decoding device, and a decoding system for decoding a B picture encoded by a direct mode at a high speed. A decoding process of an n-th macroblock (steps S103 to S115) is performed in parallel with transfer of a motion vector of an anchor block for an (n+1)-th macroblock to a buffer 106 (steps S102 and S116). With this construction, even if the (n+1)-th macroblock is encoded by the direct mode, a motion vector can be immediately calculated using the motion vector of the anchor block for the (n+1)-th macroblock in the buffer 106, when the (n+1)-th macroblock is decoded during a time T2.

This invention relates to a system for mounting an underfloor electronic equipment to a rolling stock body having an underfloor storage portion formed under the floor in the longitudinal direction of the body as a portion of the body. The underfloor storage portion comprises a guidance tool for guiding and supporting the underfloor electronic equipment formed as a unit, a body-side connector corresponding to an electronic equipment-side connector formed to the electronic equipment, and a fixing tool for fixing the electronic equipment to the underfloor storage portion. The underfloor electronic equipment comprises a moving means guided by the guidance tool and the electronic equipment-side connector corresponding to the body-side connector. The electronic equipment can be moved by the guidance tool between a fixing position within the storage portion and a removal position outside the storage portion, the fixing tool used to fix the equipment to the fixing position where the equipment is electrically connected. The present invention facilitates maintenance and replacement of the electronic equipments and shortens operation time.

An object is to smoothly perform handover at the time when a mobile terminal changes link connection, and shorten a time required for changing the link connection. When a mobile terminal 21 changes a connection link utilizing HMIPv6, the terminal transmits authentication information together with information (binding update) for changing the link connection with respect to a server (MAP 10) which manages the link connection of the mobile terminal. The MAP transmits an authentication result together with confirmation information (binding acknowledgment) of the change of the link connection, when making an authentication result with respect to an authentication server 32 to acquire the authentication result. After receiving binding update and authentication information from the mobile terminal, the MAP first sends binding acknowledgment and tentative connection permission, thereafter acquires the authentication result, and may determine whether or not to grant an official connection permission.
