A data processing method and apparatus, and a cache, a processor and an electronic device. The data processing method comprises: receiving a data processing request, wherein data that is requested by the data processing request comprises data that is suitable for being stored in at least two cache units, and main memory addresses of the data in each of the cache units are consecutive; and when main memory address information of each cache unit that satisfies a mapping relationship comprises all the main memory addresses, simultaneously performing data processing on the data which corresponds to the main memory addresses. By means of the method, a bandwidth is improved such that the efficiency of data transmission is improved.
