The invention provides a multi-core processor and a data access method. The multi-core processor comprises at least two processing cores and serial coprocessors which are connected with the at least two processing cores through a bus. Each processing core is used for reading sharing date access orders, and sending the sharing data access orders to each coprocessor through the bus. The serial coprocessor is used for carrying out serialization to all sharing data access orders received through the bus, and sequentially accessing sharing data through a local L1 buffer according to each serialized sharing data access order. When a plurality of processing cores are in cooperation, namely the plurality of processing cores simultaneously access the same sharing data, due to the facts that the sharing data respectively points to each serial coprocessor, and the serial coprocessors can serialize all the received sharing data access orders through the bus, conflict problems are solved, and then relative fixation of cooperative time is ensured.

Phosphate laser glass component loading case
InactiveCN103057843AGuaranteed to be relatively fixedPlay a limiting rolePackaging under vacuum/special atmosphereContainers to prevent mechanical damageExhaust valvePhosphate
A phosphate laser glass component loading case comprises a case body, buckles, hinges, a case cover, a case cover sealing groove and a case body sealing strip. The case cover sealing groove and the case body sealing strip are sealed in a clamp manner through the hinges and the buckles, so the case body and the case cover can form a sealed body. The phosphate laser glass component loading case is characterized in that a humidity meter and a plum-blossom-shaped exhaust valve are arranged on one end face of the case body, an inflating valve is arranged on the other end face of the case body, reinforcing ribs are arranged at the bottom of the case body, bases are arranged at the inner bottom of the case body, side rubber blocks and top fixing frames are arranged on the inner top of the case body, and case body handles are arranged at two ends of the box cover. The phosphate laser glass component loading case has good air-slaking prevention, mildew-prevention, dustproof and damping functions for loaded phosphate laser glass components.

Permanent magnet motor rotor processing technology and rotor assembly
InactiveCN110752723AReduce processing stepsGuaranteed to be relatively fixedMagnetic circuit rotating partsManufacturing stator/rotor bodiesElectric machineEngineering
The invention relates to a permanent magnet motor rotor processing technology and a rotor assembly, and relates to the technical field of permanent magnet synchronous submersible motors. The permanentmagnet motor rotor processing technology comprises the steps of stamping a to-be-stamped part into a rotor sheet with a rotor groove, a riveting area and a welding port through a self-laminating andriveting stamping machine; mutually laminating and riveting the plurality of rotor sheets to form a rotor core through the riveting area by the self-laminating and riveting stamping machine; completing the welding of adjacent rotor sheets in the rotor core at the welding port by using laser; assembling permanent magnets in the rotor grooves, and bonding magnetism isolating rings to two ends of therotor core; and drying and curing the rotor core. The rotor assembly is processing according to the permanent magnet motor rotor processing technology. The technical problems of multiple steps, complicated technological process and high cost of the permanent magnet motor rotor processing technology in the prior art are alleviated.
