Abstract: A method, an apparatus, and an electronic device for controlling memory access are disclosed. According to an embodiment, there is provided a method for controlling access to a memory including a plurality of memory modules configured in parallel. The method comprises: receiving an access instruction including an addressing field which comprise a parallel control field for controlling parallel access, a module address field for indicating a memory module, and an in-module address field for indicating an addresses within a memory module; parsing the access instructions to determine the parallel control field, the module address field and the in-module address field; determining one or more memory modules to be accessed based on the parallel control field and the module address field; and accessing one or more addresses which are within the one or more memory modules to be accessed and assigned by the in-module address field.

Abstract: Disclosed are a method and an apparatus for accessing tensor data. The method may include determining a first row address in a first memory where one or more first data items to be accessed in a logical structure of the tensor data are stored at the first row address, copying data items at the first row address in the first memory to a first buffer row of a first buffer, moving each first data item in the first buffer row of the first buffer to a corresponding location at least in a first buffer row of a second buffer, and storing data items in the first buffer row of the second buffer into corresponding target locations in the second memory.
