Abstract: The present invention relates to the communications field, and discloses a data transmission method, a device, and a system, so as to resolve a problem in the prior art that user equipment cannot correctly parse data or measure a channel due to incapability of identifying different operators. A specific solution is: obtaining a scrambling code sequence, where the scrambling code sequence is generated according to a specific sequence of an operator to which a first device belongs; scrambling data according to the scrambling code sequence to obtain the scrambled data; and sending the scrambled data. The present invention is used for data transmission.

Abstract: The present invention provides a dynamic set associative cache apparatus for a processor. When read access occurs, the apparatus first determines a valid/invalid bit of each cache block in a cache set to be accessed, and sets, according to the valid/invalid bit of each cache block, an enable/disable bit of a cache way in which the cache block is located; then, reads valid cache blocks, compares a tag section in a memory address with a tag block in each cache block that is read, and if there is a hit, reads data from a data block in a hit cache block according to an offset section of the memory address.

Abstract: A data transmission method and an apparatus relate to the communications field and are applied to data transmission to effectively reduce a collision reoccurrence probability after a device in a licensed-assisted access using Long Term Evolution (LAA-LTE) system preempts an unlicensed spectrum and collides with another device. A first device adjusts a detection moment or a quantity of detection times of clear channel assessment (CCA) of a channel in an unlicensed spectrum after the first device determines that the first device collides with another device when occupying the channel in the unlicensed spectrum to transmit data, and the first device occupies, according to an adjusted detection moment or an adjusted quantity of detection times of CCA of the channel in the unlicensed spectrum, the channel in the unlicensed spectrum to transmit data.

Abstract: A memory access processing method and apparatus, and a system. The method includes receiving a memory access request sent by a processor, combining multiple memory access requests received within a preset time period to form a new memory access request, where the new memory access request includes a code bit vector corresponding to memory addresses. A first code bit identifier is configured for the code bits that are in the code bit vector and corresponding to the memory addresses accessed by the multiple memory access requests. The method further includes sending the new memory access request to a memory controller, so that the memory controller executes a memory access operation on a memory address corresponding to the first code bit identifier. The method effectively improves memory bandwidth utilization.
