According to an embodiment of the disclosure, a processor and a method, device and storage medium for data processing are provided. The processor includes a plurality of processor cores, each of the plurality of processor cores including a data cache for reading and writing data and an instruction cache for reading instructions, the instruction cache being separate from the data cache. The processor also includes a distributor communicatively coupled to the plurality of processor cores. The distributor is configured to distribute to-be-processed data to a respective data cache of at least one processor core of the plurality of processor core, and distribute instructions associated with the to-be-processed data to a respective instruction cache of the at least one processor core for processing.
