Method, system and device for allocating logical channel identifiers (LCID) and determining logical channels

The embodiment of the invention relates to a radio communication technology, in particular to a method, a system and a device for allocating logical channel identifiers (LCID) and determining logical channels, which are used for making the LCIDs as long as a long term evolution (LTE) system capable of identifying the logical channels more than the logical channels identified by the LTE system. The method provided by the embodiment of the invention comprises the following steps that: a node B (NB) divides the logical channels corresponding to a plurality of radio bearers (RB) corresponding to relay node (RN) equipment into two groups, allocates different logical channel group identifiers to each group, and allocates the LCIDs to the logical channels corresponding to each of the plurality of RBs corresponding to the each group, wherein the LCIDs of the logical channel corresponding to the each RB in the same group are different; the NB establishes a correspondence relationship between an RB identifier and a logical signal identifier, wherein the logical channel identifier includes the LCIDs and the logical channel group identifiers; and the NB informs the RN equipment of the correspondence relationship. By the method provided by the embodiment of the invention, the performance of a changed system architecture can be guaranteed.

Heat treatment process for 65Mn spring washer

The invention relates to a heat treatment process for a 65Mn spring washer. The heat treatment process comprises the following steps: blanking; electric spark perforation of basic bores; linear cutting and forming; correction by a fitter; heat treatment; performance test; and surface treatment; wherein during quenching in the step of heat treatment, firstly, the 65Mn spring washer is subjected to preheating which means the 65Mn spring washer is put into a quenching tool heated in advance, then a quenching furnace is heated, charcoal is added into the quenching furnace, the quenching tool is placed into the quenching furnace with a temperature maintained to be constant, then the quenching tool is taken out, the 65Mn spring washer is put into the quenching tool, quenching is carried out immediately after thermal insulation, and the surface of the 65Mn spring washer is coated with an anti-oxidation decarburization paint before the 65Mn spring washer is placed into the quenching tool. According to the invention, the charcoal is added into the quenching furnace for generation of protective gas, the anti-oxidation decarburization paint is coated on the surface of the spring washer for prevention of oxidation and decarburization, so desired performances of the spring washer are guaranteed.

Single instruction multiple data (SIMD) vector processor supporting fast Fourier transform (FFT) acceleration

InactiveCN102495721AGuaranteed performanceAvoid hardware overheadProgram controlMemory systemsHardware accelerationAddress mapping
The invention discloses a single instruction multiple data (SIMD) vector processor supporting fast Fourier transform (FFT) acceleration, which comprises a control unit, a calculation unit, a storage subsystem, a storage weaving unit and an address generation unit. The calculation unit supports quick processing of various vector calculations. The storage subsystem comprises three storage groups. Each storage group comprises four storage bodies, the bit wide of a single storage body in each storage group is a plural character, and the storage groups support plural vector calculation with concurrent four-way data and real number vector calculation with concurrent eight-way data. The calculation unit, the address generation unit and the storage weaving unit are connected with the control unit. The address generation unit generates required operand address sequence, coefficient address sequence and result address sequence. The storage weaving unit and the address generation unit are connected with the calculation unit to achieve address mapping of the storage bodies. The acceleration efficiency of the SIMD vector processor to FFT/ inverse fast Fourier transform (IFFT) calculation corresponds to a special hardware accelerator. The SIMD vector processor avoids huge extra pay expenses brought by use of the special hardware accelerator, and is suitable for being used in a real-time signal processing system with a large amount of long vector calculation.
